Any Prusaslicer 2.x experts in da house?

I keep running into an issue wherein PS (stands for PrusaSlicer and Piece of you-know-what ?) insists on including color changes upon slicing. The summary shows a total of 3 colors, but the model is just 1 color, and the vertical scroll bar has no + areas. Is this a bug?

Interestingly I have not run into this. Here is a video that talks about the Prusa Color change features. Make sure you have not added a color change by mistake.

I finally just started over with PS, and the problem disappeared ?
