Map opening and closing over and over

Has something to do with the force move keybind. I bind it to my mousewheel, and it works fine in live. But on the PTR, the map opens and closes all the time. Doesn’t matter what key I bind it to. And it’s not 100% of the time upon keypress. Happens like 6-7 times a baal run or something.

But again, I go back to live, with the same settings, and it works fine.
