Some V8 characters "jump" upwards when using IK moves

DrHemulen

I'm having a bit of a weird issue with some of the Genesis 8 characters. When I select a piece (like a hand) and move it to pose the figure via IK, the entire figure "jumps" upwards, about 10cm to scale. It doesn't happen when I rotate or pose using powerpose. It happens every time I try to move it, so it just keep going upwads, making it extremely hard to pose. I can of course move the figure down after posing, but that's not very efficient. Zeroing pose or figure snaps it back to the ground plane, but it starts jumping upwards as soon as I select a part and try to move it.

As I mentioned, it only happens for some of the G8 chars, which makes it even weirder. From my collection so far:

Jumps:
Elizabeth
Rebekah
Victoria8
 

Work fine:
Daphne
Genesis 8F
Phoebe
Olympia
Sarah

I have been using DAZ with Vx for years, without this issue. I went back and checked some V7 characters, and could find none that had this behaviour, so it doesn't seem to be a general error introduced when I upgraded to DAZ 4.10.

Any suggestions?
