I think I found a small bug. Whenever I try to filter IS EMPTY for a field type “Collaborators”, the filter does not work.

I think it’s because collaborators at the end of a multi-select field and the filter would have to query the array of user IDs if one is found or not.

If you could check if you got the same result

It appears to be working as expected for me or perhaps I have misunderstood something?

Before filter:
