Hello!  
I work with Slicer 4.11.0 , win10  
The problem is: In Segment Editor Paint mode modify several slices together (see photo). If it is not an error, I would like to know, how to deny such modifications. In my work I need to modify only one slice simultaneously, and then use Fill between Slices mode.

This looks like the effect of a “Sphere brush” option in your Paint tool. Can you verify if it’s turned on?

If not, please provide details what kind of image you are working on.

You are right. That was “Sphere brush” option turned on.  
Thank you!
