I hae a null component and a null TOP. the component display icon is off, the null’s on.
I select both, ctrl-c, paste, ctrl-v, and now both copies have the display icon on (only the null top copy should).
I can not reproduce this in the latest build. Does this happen in a certain file, or can you reproduce it in an empty sessions as well?
There is also a “Preview On by Default” option in preferences under Tiles, but trying this in both settings I could not reproduce.
