Steps to reproduce:
1. Create a few of recordings in a series
2. Use Bulk Action to Edit Metadata on a couple of recordings and change the series
3. Use Edit Metadata on single recording and change the series.
The Series doesn't change
The series is changed on both recordings to that
Workaround (if any):
Individually edit the recording's metadata
Note the series is correct though if you go back to the editor, but not on the recordings tab nor the inspection page.
