Changing ignored tags in AP configuration does not work after once setting any tag as ignored

[baschi29]

Describe the bug
After setting two tags as ignored in the AP configuration window of the integration I cannot change them anymore. Trying to save any change fails with

value must be one of ['0000021A4B663B1F', '0000021F7DF73B17']

where the IDs are the IDs of the two currently not ignored tags.

To Reproduce
Steps to reproduce the behavior:

1. Go to the integration page
2. Click on the gear icon next to an AP
3. Add a tag as an ignored tag
4. Save and close the Dialog
5. Open the Dialog again
6. Change the ignored tags and try to save

Expected behavior
Saving the changed ignored tags should work.

Screenshots

Additional context
I Actually do not need to change the tags to get the error, symply trying to save again is enough.
