Magic bullet Glitches

Hello, Basically I discovered this problem when I was done with my edit. When I was putting my quality and played the edit, it glitches suddenly.. I don't know what's seems to be the problem. When I removed mbl, the quality didn't glitch, but when I added it back, the glitchy thing came back. My mbl was fine before, it's not glitchy back then and idk what's really wrong. Do I need to re-install mbl?
