Expression string returning false when it should be true

I have made a few custom stats and I'm trying to use them in Range Research. I've been testing them one by one and it finds 0 players since the expression string returns false. I made a custom stat called "RFI 2bb CO"

When I test the stat it returns a lot of cases:

When I use the expression string "Cases(RFI 2bb CO)>0" it returns 0 players.

I already cleared stats and rebuilt them and then rebuilt the range research report. I'm going crazy trying to understand why. Any help would be much appreciated. Thanks!
