If you added those now discontinued tag shape invitations from anywhere but your backend of your store then the tag shape will show in your collection even after you have switched to another shape and when your customer clicks through to the product it will also still show as the tag shape until you remove the invitation from the collection and then add it back. But you need to add it back from the backend of your store to get rid of that tag shape in your collection. The shape is correct in the marketplace after the change but it seems you need to remove the entire product from the collection and then add back from the backend to rid that tag shape from your collection. You might be able to add back from the product page if you are seeing the corrected new shape on the page you are viewing, I did succeed doing it this way too but to get the new shape to show on the product page you need to go to the product page not from the collection but from the backend where you see the new shape or from your recently viewed products at the bottom of your screen. Hope this makes sense and helps.
