Thank you so much for your answer, Péter!
Somehow a “relief” to know it’s a bug.
But good grief! I think I’d rather wait for the bugfix then 😀 (I’m using the complex profiles, so I don’t know what’s actually displayed with the object, which makes the workaround undoable).
Hopefully it doesn’t take too long to fix. Will it be retrofitted into AC 24 (which still got this issue) and 23?
