Unable to swap weapons in versus bug?

Let me explain, I’m a die-hard old school brimstone Gears Of War veteran. I’ve played them all and just recently I skipped from 3 - 5 entirely. I didn’t buy an Xbox One until recently. I’ve played allot of matches trying to tweak my settings to compare my personal play style with 3. Unfortunately somewhere I bugged my gameplay. I turned my gore settings off - on. I can’t snap necks on meat shields. I grab a power weapon in ranked and if I’m not vibing with it. I’m unable to simulate the trade with another player. Does anyone have a solution for this?
