Fortnite doesn't save the settings?

Don't know if any of you know that. In fortnite, every time I reload it, I have to turn on the sound, i.e. 3d sound. When I do that, it automatically changes the graphics, which I then have to change again. It's not bad, but it is very annoying. Does anyone know advice?!

Set up your headphones as a stand-alone audio device

But that has nothing to do with the graphics, does it?

Probably yes
