nametagged axolotl despawned

The realm I own is updated to the latest 1.17.1 features but axolotls are still bugged. I name tagged an axolotl and have picked up and placed it from a bucket numerous times and it still despawned. I am very upset and would like this to be fixed soon. Most unnamed tagged axolotls are still in the realm but I am upset that my one name tagged axolotl despawned without a trace. Give me back my beloved Passerine please.
