Marking names

What's the issue? Please include any error messages you receive and as much detail as possible.
When I read the news post and saw the new reviving item (Canopic Jellyfish), I instantly bought it and used it on my favorite deceased lioness. After using the item, her markings' names disappeared and got replaced by "no markings", though the markings themselves are still visible on her image.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
1. Bought the Canopic Jellyfish from the event shop

4. Refreshed the lioness's page and marking names disappeared
