Have you checked your IK Normal Planes?
As you may see the fingers of your character won't be able to bend in a correct way.
IK Normal Planes can be easily set by clicking on the related toggle boxes in the upper right corner of your limbs.
The IK planes are now in the right direction.
There is a tool to help you to check if the limbs IK planes are correctly defined or not. Click on "Check Skeleton Mapping" button
If the IK bend in the correct way, save back your gcha and render again your entities, the problem should be corrected.
Notice: If the problem persist, load your gmos and check their IK planes. You may have to make the same corrections on the gmos and saving them back.
