I’m trying to use Krita for some map work. The image I’m working on suddenly duplicated itself and mirrored itself on the right of the page. So now I have both my original image on the left and a mirror image on the right.
How do I undo it?
Press M again?
Michelist
Nope.
That just mirrors the already existing images. 
So you mean what you paint left shows on the right too and vice versa? Do you have such a symbol on your canvas:
And if not then we need a screenshot of your complete Krita, including status bar, title bar, open and fully viewable Tool Options Docker, that is usually the tab below your color selector and for enlarging the dockers have dragging areas on top and bottom, and your layer stack should at least show the layer in question but of course as much layers as possible (you can even break it out of its dock via drag & drop).
Michelist
No. That symbol actually happened/appeared earlier - not sure how. But I got rid of it pretty easily.
I only want the image on the left.
And since I just see it, you have to enable the view of your Toolbox too
You know how to get dockers into Krita, a I asked for the Tool Options Docker, don’t forget it …
But take your time, for now I have to turn the lights off, it is already 4:39 AM and I’m no robot, I need to sleep too …

Tool Options open at upper left and Toolbox along top of the first and secod image.
Second Image shows Dockers.
I don’t know how it started mirroring, either by accidentally using the mirror tool or the multibrush, probably. But now, with the pixels already on the layer, you can simply erase them or draw a selection around them and cut them away.

probably flipped the image or something…
But how? One six layers at once?
That’s a good ‘Gordion Knot’ solution. I was hoping to understand what happened and reverse some command and undo everything all at once.
Anyway, I made a copy and erased all the layers, and am proceeding with fingers crossed.
I’d like to thank everyone for their kind help.
If someone can help me diagnose the cause, that would still be appreciated.
In cases this happens again, Krita has a docker called Undo History, it sometimes gave me hints about what I did wrong, but the undo history doesn’t persist through sessions or file closing/reopening. In your cases it would have shown you if you used the multibrush accidentally. Activating the mirror tool that Michelist mentioned would have not been in the list, though.
For reversing actions, you can usually try to undo CTRL + Z the last steps, at least as long as you don’t close a picture or save it to disk. I’m using here 800 steps buffer, you can set it in Krita’s settings.

I knew about this. But I couldn’t the Docker (which I couldn’t find) so I immediately went to edit and undid a series of actions assuming that would achieve the same effect - although the only Undos available were brush strokes. I could see a series of actions (undos) so I undid a few hoping to arrive at the one that caused the mirroring, which I assumed would be a ‘property change’.
I found it this morning (it was the last Docker and the only one at the top of the list on the other side, which I initially didn’t see.)
I’m assuming the undo I’d be looking for is a ‘property change’. Could I have reverted this alone? Would the images above the offending property change not show the mirroring?
If it was a registered action, listed in the history, it should have been revertible.
Michelist
Would the undos above this revertible step not show the mirroring? (The Undo history is still available).
I remember the problem came after I added a layer.
Currently, we don’t even know what exactly happened, perhaps you used the multibrush, maybe something else, then you would revert both sides of what you painted with it.
If I were you, I would fix it as good as possible and try in the future to paint with more awareness of the things happening on canvas.
Michelist
The mystery (bug?) remains.
I don’t think it was the multibrush. I never changed brushes on this work (I would have noticed) and the multibrush tool is not near anything I was clicking. Would the multibrush mirror all my past work on multiple layers, because that’s what happened.
I did have a question about reverting changes…
