No problems for me with genesis facial morphs - all work including phonemes ( although i do not have mimic to see if working with that)
But short answer is sliders work all levels Genesis Model or Head.

EDIT - WEIRD !! Just checked version I’m running which is 149 not 172 I did a system restore a couple of days ago which must have changed it because I know I installed 172 which I will do again if I can find it in my account which of course never specifies a build number - and you cant sort the items like you used to - Daz !!! Dah !
