SexLab's creature animations disappear when new ones added

[Princess Cake]

I really like the preset creature animations installed with the latest SexLab but whenever I add some new ones like FunnyBizness' it seems like SexLab just dumps the whole creature folder it comes with and only allows newly imported stuff >.>

Am I doing somethig wrong or wtf? I'm using SL Animation Loader and run FNIS anytime I mess about with animation packs.

In Sexlab's MCM tab, you can "Register Animations".  It will refresh the list of available animations.  Do this whenever you deselect, select, or add new animations.
