Can't bulk edit metadata of clips in Premiere 22.5 project

Hello. I've got ~100 clips shot on two cameras that were timecode synced. I'm trying to assign camera labels to the clips to create a multicam sequence that's timecode-relative.

When I select multiple clips, I am unable to change their Camera Label metadata tag in bulk. I can change them on a clip-by-clip basis. The problem appears to be the same as what a user posted about here back in '17. I have been able to edit clip metadata in bulk on this version of Premiere... just not today?

Thoughts?
