Crooked somersaults, need some help

I’ve noticed when i am doing a trick that involves a somersault, such as a braintwister or split the atom, the yoyo falls to the left. I am right-handed, also. Does anyone know why this is, and if so how can I fix it? Thanks

falls off the string or tilts? The only reason i can think of is if you doing your sumerslauts crooked.
