To be a bit more detailed, what you're likely running into is a rogue "Joint Controlled Morph" (JCM). Consider a character whose knee is bending. Sometimes, the top of the calf and the bottom of the thigh don't "fold up" the way that a PA would like when they're building a character. So, what the do is:
- Bend the knee
- Create a morph that fixes the bits they don't like around the knee
- Tie the morph to the knee bend
This why it's called a "
Joint Controlled Morph."
Now, when a PA does this for one of his/her characters, he's
also supposed to tie it to his
character morph being selected, so that it doesn't trigger on other characters. But sometimes they screw up. Or, sometimes, when a user is trying to create a morph of their own, they inadvertently fiddle with a morph and break it.
Bottom line - it's almost certainly
not the fault of the G8F character itself - it's something else that's adding itself in when it shouldn't be.
Just as an example, consider the "George" character for G3M. He's pretty, well, "rotund," so making his joints work nicely takes some doing. Thus, if I have George in my scene and bend him forward at the abdomen, there are a lot of "hidden" morphs that come into play. I said earlier that you would find them on the "Shaping" tab - I was mistaken, it's the "Parameters" tab.
Put your G8F into the scene, bend her so that the problem shows.
Then, go to the "Parameters" tab, click on the hamburger menu, and select "Show Hidden Properties."

Then click on the "Currently Used" item, and look for anything other than the bend that you selected.

If you find something, click on the little gear button and a dialog will come up.

The contents of the dialog may give you a clue as to what the rogue morph is. If you can figure out the bad morph(s), we may be able to track back to what "product" it's contained in.
BTW, I've seen this happen to any number of people over on the Daz forums, so don't think you're alone in this...
