Can't Change Insitu for Throw Blankets

I have not been able to change insitu images for throw blankets for the longest time. Is there a bug in this issue?

I see that the change options limit to only the product images (no models holding the blanket). I can change to one of these 3 images, but no way to change to the models holding the blanket.  Why??

I can’t make any changes…period!

There was something a bit back about the in situs changing because of model-release issues and Z was no longer allowed to use those people. I dont remember all the details - there’s probably an announcement about in the News section? - but maybe it’s related.
