Weapon selection glitched?

So my weapons are inverted, what I mean by this is that lancer is on my left d-pad when in the customization menu I keep changing it to the right side and when I get in a game it’s on my left side and my gnasher on the right side and no matter what I do nothing changes.
This a problem because I’m used to change my lancer for the weapon pick ups and every time I try to change my lancer I change my gnasher.
