Sketchup Glitch. Geometry issue

Hello Guys!
I seem to be having an issue. Geometry in the model seems to be messed up. When i make into a group, it looks normal, but while entering or editing the group, the geometry starts to get messed up again. Image attached below. The shape in the image is supposed to be a circle but isnt when editing.


It’s hard to tell from your screenshot but it looks like clipping. Do a search for ‘clipping’ on the forum and you’ll some info.
