Reposting this because the topic was closed without solution. Just ran into this problem. I have a nested swappable component and after swapping the component the swapped component had a purple outline as though it would be selected which it wasn’t.
When I duplicated the Instance the outline was gone in the duplicate. So I deleted the ‘faulty’ instance and all was good. So that could be a workaround. Hope it helps someone.
Happy designing and bugchasing to everyone!
