Filter only show items that have referenced item set

So i have a rather simple question, and it should be possible, but it doesn’t work.

I simply want this for a Collection List:

Only show collection items that have a specific (multi-) Reference item added.

I choose a reference item called “Good Against” and select “Is Set”
I expect it to only show item that have something set - but it’s doesn’t work.

So all collection items that don’t have “Good Against” set should not be shown.

But instead, i see practically every item. Why doesn’t this work?
