Facebook Shops Integration "item issue" with online editing as the reason?

[cap377]

I finally was able to properly integrate my Square inventory with FB/Insta but am getting this "issue message" on the majority of my items: "This item was added to your catalog using a partner platform. To avoid your manually made edits being overwritten in the future, update it on your partner platform." However there is nothing to edit as far as I can tell, I haven't edited anything, and FB isn't giving me any other error message but this one.

The issue is keeping these items from showing up in my FB/Insta shops (which I've now turned off until I can figure out the problem) - any item with this issue (and the little yellow exclamation point) are not available to sell on FB and won't show in collections, ads, etc. 

Any similar experiences or help?
