@AdornDC - I just went to my favs, found a sold one, clicked on the red heart which cleared then it brought up my lists of collections. I then clicked to remove the checkmark by Favorites, clicked Done, then refreshed the page and it was all gone. Hope that makes sense and works for you. Actually quite simple once you do it!
Note that all my sold ones still have a heart, at least in my complete lists of favs from the heart on upper right top of my shop front page....try going in from there if you haven't. Also, I have no idea if it affects anything, but my favs are all private.
