Decapitated (actually not), trouble with fatality mod.

[staspidaras]

Install a killmove mod (Violens), that adds % chanse to make a fatalities to enemy, it works correct, but ran into a problem with decapitation anims when i fight with female enemies - when my character must decapitate one of them Skyrim play animation that shows how head chopped off and flies to the side, but after it head returns to it's place.
I suppose that the problem is in a certain parameter of female models used in the settings, but I'm afraid to change something and unknowingly ruin the whole game, maybe someone knows how to help me?

I also use this mod, but an older version, without SKSE and SkyUI.
beheading 90% adjusted and killmove 70% adjusted, I never had problems. 
even the cultists with helmet from Solstheim lost their head.
