Anyone have Lucia Shoes? How to fix the toe pose? Sole bends when it shouldn't

Gator

It's not horrible, but the little toe (Daz Small Toe 4) isn't touching the sole.  But if you bend Toe 4, or use pose control Pinky Toe bend, the sole which should be non-malleable moves along with it.  How to adjust without jacking up the sole?  Why did it pass QA like this?
