(pc desktop) Left shift facial expressions wont show

I have my fx layer all set up with different blendshapes on both hands, but the left hand blendshapes wont show unless I toggle any of the right hand blendshapes. None of the tutorials bother to mention anything about using the right hand whatsoever either, they focus solely on the left which is incredibly unhelpful

nevermind, i figured it out. turns out only the left hand orange default idle box should be checked where it says “write defaults”. The right handed one must NOT be checked. And it turns out the first grey box at the top which is F2 for both hands should both be empty
