SketchUp Styles Changing Automatically

I’m having a weird issue since updating to SU2021… my styles are changing automatically, in problematic ways. For instance, I’ll turn on section planes to see modify a section cut, then turn them off… and when I go switch to another scene, my section planes are turned on, and the pre-assigned style for that scene now has section-cuts on, even though I never updated that scene or style. Happens with lots of style attributes; axis on/off, hidden geometry, etc… it isn’t happening all the time, but when it does it is obviously frustrating, in that I have to roll through all of my scenes and fix the style attributes, sometimes over and over again. Any ideas what is happening here?

It would be helpful to see your Sketchup file that is showing this. Can you share the file?
