Despite the filters being page specific the names you give them must be unique across all filters. How am I supposed to know what I already used if I can’t see them?

Adding a custom value to a field in a filter breaks your ability to edit it or add more than one thing to it. This makes the In/Not In functionality useless as I can only choose one thing.

Once you’ve used a field in a filter you cannot use it again and have to instead go in and edit that field. This makes tracking a process of narrowing down results more difficult as the history of what I had chosen before is gone.
