Hello, I do not think it is the same problem, nor is it the one I mentioned recently about the advanced color selector (they may be related in their base, but not in the effect).
The problem is … weird . If I press the color blue on the bar, it immediately turns orange, and paints orange. If I put it in orange, it goes in blue, and it paints blue. If it is in blue, and I click on the box, it turns orange and vice versa. With the other colors as well, but the changes are minor, depending on the color, more or less.
In addition, this also happens in the specific color selector in Lab mode. There I have not stopped to check which one it changes to, but you click one and it changes to a totally different one. And paint with the one that krita has changed you.
