Named Villagers with jobs vanishing. Glow signs stopped glowing.

My world is on a 2 player realm where i play cross platform with my daughter. My villager trading hall has lost 8 villagers out of 9 in total the other day. They were all named, they had all their jobs locked with purchases. This was annoying enough, but today i log on and the 2 zombie villagers I'd trapped (also named) had vanished....One had vanished before i cured them yesterday, so i cured the 1 left over. But today he is gone too. This is driving me crazy. I take a lot of time to do these things just for them to vanish with no reason other than it's bugged.
