Trying to sync table for limited employee view and I can't get it to work

I am a real estate agent and I have a number of listings I work on.

I am trying to add a synced base from my master base, where only collaborators can see listings assigned to them. I can get my master base to sync with a new base, but when I try to filter by collaborator the user’s info is replaced with “invited user”. I can filter by typing in invited user, but this won’t work as I add additional collaborators. Can anyone help? Thanks!
