We probably have around 50 or so named mobs in the area. 12 are villagers and the rest are assorted animals.
They were only about 30 blocks apart. They were named in separate sessions (months apart) and had unique names. Seems like it could be a hash table collision or something similar to me.
See my comments in MCPE-101295
I find that I randomly lose named entities when I add a new named entity. This has happened quite a few times, but always around naming something new.
Disregard. It's mending. I'd close this if I could
