Game inverted X axis suddenly

I played a match before this happened with everything normal, and no inverted mouse controls. But the next match I play, for some reason, had the X axis controls completely inverted and spoiled the whole game. I tried deleting all the settings from the Documents/Battlefield 1 folder, and also resetting the settings, but it didn't do anything to fix this problem. This only affects the controls while in game, but the cursor in the menu and everywhere else is normal and not inverted. Please give a solution to this if you have any. Thank you 🙂.
