False prefab overrides generated by Ui Layout ?

Hi all,

I am finding lots of prefab overrides within my Ui system that I did not create. My Ui system uses many layers of nested prefabs, prefab variants, and Ui Layout Groups (usually Horizontal or Vertical). I keep encountering the following:

1) Change the structure of some 'low level' Ui prefab in the Prefab Stage Scene.
2) Looks correct in the Game / Scene view of the Editor from within the Prefab Stage Scene.
3) Leave the Prefab Stage Scene and go my normal Scene.
4) Notice that the recent Ui changes don't look correct.
5) Dig through the Ui system in the Scene and find many prefab overrides that are overriding my recent change.
6) Manually remove these prefab overrides and finally see that everything is correct.

As far as I can tell, these overrides are being generated from a parent Ui Layout Group.

Is anyone else seeing this?

Thank you

 

Upgrading Unity seems to have addressed this issue. Apologies for the false alarm.
