CC3+ imported animation does crazy hair flipping

I’ve imported a character with animation into UE 4.26 from Character Creator 3+. The anim plays well and I’ve added logic to loop the anim when it reaches the end. However, when going back to start the hair goes crazy and flips all over t\heeh place (see link below).
Any ideas on how to stop this crazy hair flipping would be appreciated.
Thanx,
ZM
