So, my XBox one controller has started breaking down, but still technically worked. But I decided to get a new controller during the sale, an 8bitdo Ultimate 2 Wireless Controller

However, using that controller messed everything up, making my right thumbstick suddenly move around the mouse and the buttons aren't doing what they're supposed to in game. (RPG maker)

So, decided to switch back to the XBox one controller for now, but now that is messed up in the same way. I feel like I'm going nuts trying to figure out. I've poked and prodded at the settings, looked at guides that seems either out of date or doesn't work for some reason.

Just... please tell me someone can help me fix this. I miss playing my games, lol.
