Opening file in GRIP spams console with UI errors

[rlee287]

When loading a file, this gets spammed into the console. The part that says 'Button.delete' is different each time, so it must be referring to different GUI elements.

This isn't anything that breaks the UI but this is something we could do to clean up our console spam.
Thanks!

It could probably just be deleted and it would fix the problem

This hasn't been resolved.
The CSS is still wrong.
