BCG not fully cycling

I have a 6ARC build 18” barrel with a geissele H1 buffer and braided spring. My rifle isn’t cycling properly at first I thought it was the magazines having an issue but I took a video and it looks the BCG isn’t fully going back. It’s ejecting the cartridge but not grabbing the next round or locking back on empty after the last round. So this led me to believe it’s not fully going back. Any ideas of what I could do or try to solve this issue?
