Exclusive Fullscreen Issue (Apex legends wont go into true fullscreen)

Hi guys,

I posted this onto the subreddit but figured I'd crosspost to here after seeing Jayfresh's post:

Bit of a strange one and no huge deal as it's not exactly a lot of effort to just hit ALT+Enter, but I'm not sure why it's occurring; I'll open the game and it's in windowed mode, I have Fullscreen selected in settings already, but I have double-checked as well, I ALT+Enter and it goes to fullscreen and the next time I open it, it'll be windowed again.

More of a nuisance than anything else, any suggestions welcome, cheers!
