Dolphin forces 23.9Hz refresh rate

[Rossa]

I just installed Dolphin. It is version 5.0-15716.
Whenever I switch to fullscreen mode, my monitor refresh rate gets changed to 23.9Hz, and it doesn't go back until I go to my advanced display settings in windows and set it back myself.

I can only play in windowed mode, or at a super-choppy low refresh rate.
