Hello and welcome to the forum
I’m surprised that there’s a difference between 4.1.1 and 4.4.5 in this situation.
As far as I know, krita only recognises a ‘stylus tip’ and an ‘eraser tip’ which is actually treated as a second/alternate brush and can be used as such to use any brush preset you want to.
Are you alternating between 4.4.1 and 4.4.5 by using a portable .zip for 4.4.5?
In Settings → Configure Krita → Tablet settings → Open Tablet Tester, you can draw on the grid and note what is detected in the event record on the right side.
Just bringing the tip close to the tablet surface will tell you what it is recognised as.
Can you do that for each end of each pen for 4.4.1 then again for each end of each pen for 4.4.5 and see if there is a difference?
