Creature animations on only one actor

[TheHolySin]

I have a problem with creature animations (mostly with hentai creatures) where from the 2 actors only 1 starts the animation and the other one (always the receiving) just stays inside the other actor, doing the idle animation.

 

I tried resetting the animations, and re-installing fnis-creatures but it did not help.

Also I don't know if it is related, but while fnis recognizes teh creatures addon, sexlab does not.
