TS3 Overwolf Overlay Not Working Properly

Since a couple updates ago, I can no longer hide the Full Window for TS3 while in-game. I used to be able to open the Full Window with the hotkey and then hide it with said hotkey, but now I can’t and if I press the X it just closes my entire TS3, can’t even minimize it.

I’ve already contacted Overwolf support and they stated that it was probably more of a TS3 problem than an Overwolf problem. I’ve already tried to reload and reenable the Control addon.
