What gameplay feature is this bug affecting?
Applying the Canopic Jellyfish item on lethal cubs

What's the issue? Please include any error messages you receive and as much detail as possible.
I can't use Canopic Jellyfish on some of my lethal cubs. They were purchased by me while they were alive with their mothers, and I returned those mothers to the owners after the cubs passed away on my account. All of these lethal cubs are in my Pride Dynasty, but they also indicated as if they are in other person's folders, the same place their mothers are right now.

The same problem occurred on my side account with my other lethal cub, which I purchased already frozen and obviously without a mother. After some time I retired this cub on my side account and added it to the store of my Pride Dynasty, but the cub is also listed in another person's folder, the same folder as their living mother. And for this reason I can't use Canopic Jellyfish on this cub as well.

I assume the problem happens when a lethal cub has a living mother who has been sold/transferred to another person and is alive at the time of attempting to use a Canopic Jellyfish on that lethal cub. The other lethal cubs whose mothers stayed on my account or were chased out of my pride by me don't have this problem.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
The problem occurred with these three lethal cubs:
1. https://www.lioden.com/lion.php?id=794173145325
2. https://www.lioden.com/lion.php?id=794172168120
3. https://www.lioden.com/lion.php?id=794166616346

And a lethal cub from my side account with the same problem:

Any screenshots you can provide us with?
Here are my Pride Dynasty lions (I have highlighted three lethal cubs of concern and provided their links): https://i.imgur.com/za6F46D.png
And here's the list of lions in the Canopic Jellyfish (and those three cubs are not there): https://i.imgur.com/vwFpdnG.png

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. I purchased a living lethal cub while they were nursing from their mother
2. Three days later when the lethal cub passed away, I put the cub in the store on my account in the Pride Dynasty and returned the mother to the past owner
3. I went to my hoard to use a Canopic Jellyfish item on this lethal cub, but this lethal cub is not in the list of lions to choose from for revival by Canopic Jellyfish
