Unreal Engine Issues and Bug Tracker (UE-28374)

Description

After creating a component in code and placing an instance of the code class/blueprint into the level, the component will still show as inherited if the component is removed from code.

EDIT:
Included screenshots of actor placed before closing editor / removing component and after restart

Steps to Reproduce

Write code for a UActor (or derived from) that has some component that is edit anywhere
Place new actor in any level (Note: we made a base blueprint first, but I don't think that matters)
Make changes to this instance (Turns out the local change isn't necessary)
Save the level
Close the editor
Remove the component from the code for our new actor
Reopen the editor and our saved level
Notice - the component is still present on the instance in level and marked as inherited
