Potential Trader Llama Despawn

Hello,

It's a little hard to tell, but I think my tamed trader llamas are despawning. It's possible they could be dying to wandering mobs, but I don't see any whenever I'm around.

I acquired them when the wandering trader's leads broke. I tamed them, put chests on them, and bred them to make more. I was breeding them for strength and was using carpets to keep track of my strongest ones, but sometimes when I returned to my pasture I noticed that the carpeted llamas were missing without any sign of their chest or carpet.

This issue affects my trader llamas both that were acquired from wandering traders and trader llamas that were bred in my pasture.

I expected at least the bred llamas to remain after being tamed and given chests, since other tamed mobs seem to avoid despawning.

It’s hard to provide any additional information since the llamas and all their stuff are just missing, but if there’s anything more I can do then please let me know.
