Animation export bug

[SoulEater 6]

Hello, i'm trying to export some animations.
And i've noticed a bug, when i walk/stop the character becomes invisible for a sec fraction and that's annoying.

It happens even to mobs, i've tryed a lot of things to fix but i have no idea of what could be the problem.

(I use the ricky 2.4 converter tool.)

Hope somebody could help me, ty.

Here an example gif(don't look at the bad animation,it's just a test):
