Kristian (my brother from another mother),
Good to hear from you.
I think you may have touch on the issue; its an opening label that reads the story, ID, opening size, and relational zone data from the window/door. I just tested my wall label and it can be selected immediately though it also reads a variety of data. I might try stripping out the possible data from the opening label and see if that indicates what causes the issue.
