Possible Roadhog 4 Fader Issue

I hadn't noticed this before, because, frankly, I hadn't utilized this certain fader on the console yet. The problem is with a certain Fader, when I slide it from 100% to 70% it is fine, but then at 70% it drops the output of the stack immediately to 20% and will stay there until the actual fader reaches the 20% mark on the console and then will travel the rest of the way to zero normally. And the same is true on the way back up the fader. It is fine from 0-20 then stays at 20% until the fader reaches the 70% mark and then continues fine for 70-100. These aren't exact numbers either, it could happen at 71%. I'm just saying around that spot. I am assuming this hardware related unless I am not thinking about something.
