I'm stuck playing the same factions over and over

Not sure if anyone else is experiencing this problem but I am constantly stuck playing the same factions nonstop in Galactic Assault and Conquest.

It’s always Rebels, Resistance, and Seperatists. I really miss playing as the Empire, First Order and Clones, and I can’t remember the last time it happened. I’ve bene playing Kyber for weeks now, almost daily, and I can count on one hand the amount of times I’ve seen the other factions.

I’ve looked all over the menus to find a space to place a preference or anything that might control this, because it’s been going on so long that I’m not convinced anymore it’s chance. There has to be something in the code that’s forcing me into these factions on every match.
