FlexTools Extension

I’m having a very strange issue and I think it is tied to FlexTools/WallCutter….sometimes when I open up a model again a wall cut will appear on a wall where there was none before but it’s inline with a cut on an opposite wall.

For example in the image below; the door circled is part of my model. When I opened the model today the cut in the opposite wall (outlined in the dashed red rectangle) appeared. There was never any opening/door/window etc before in that opposite wall. This is the third time I’ve seen this behavior. When I inspect the original cut at the door wall cutter indicates it’s only set to cut two faces
