enhance listing

Every day or so, I get another listing in Manage Inventory that says Enhance Listings. I edit the listing and finish. No problems until today, when I got this message:

I clicked edit and went to stone, but…

What am I not getting? I don’t see 3 anything anywhere.

Did you click to save after looking?

I do see 2 anyway.

Yes, I clicked “save” from Manage inventory, and it saved. However, I still can’t finish from “enhance listing”.

I saw only 1 stone mentioned in “material” and 1 under “gem type”, but none at all in “stone” or “stones” attributes.

What about those 2:

I tried again from Manage Inventory > edit, and removed ALL references to stones — and Enhance Listings now reads as OK. Stupid system.

Thanks Dreamscape and Oneida for trying to help.
