So my villagers keep disappearing or changing Jobs or something.

First noticed this when four of my Farmers (each having a trade of Wheat, Beet, Potatoe and Carrot) who were named as well for their first trade and at maxed level disappeared only to be replaced by 4 new farmers who were not named and only had Beets as their first trade and were level 1. 

Now I am not sure what caused this, However this continues on over to my Librarians as well. I had 3, each were named for their First Enchanted Book Trade and were maxed level. They have disappeared as well.

I have searched my village and the surrounding area and I cannot find any Villagers that are named and none of my villagers are maxed level anymore

I have also had this happen to my Armorer, Toolsmith and Cartographer. They were not maxed level but they were at the third stages of their trades and those are now missing too. They were also named. 

The odd thing is, is that the number of Villagers I have has not decreased at all. In fact it seems to be growing at a rapid pace. I have more villagers then I do beds. 

There are also times when I find villagers of the wrong profession at the wrong job sites. For instance I have found Cartographers at the Composter and a Fisherman at a Blast Furnace despite a Cartography table and Barrel being available and not being worked at by another Villager. 

Now I have tried increasing the number of beds to match the number of Villagers to see if maybe that was the cause. It did not help. My villagers kept disappearing only to be replaced by new ones with different professions. I checked all my Job site blocks and all of them are still in place and are untampered with.  They have not moved from initial Spawn. Any sites I have placed myself have not left their initial placement points either. 

Now I know the Village and Pillage Update is rather new and that I am still learning it. However this does not seem like it's supposed to happen normally in the game.

Other things I have done is uninstall and reinstall my game (as it is a digital copy) thinking it might be something with the download. I did this 3 times across 4 different worlds with the same results still occuring. As such, I am at a loss as to what it could be other then a bug or a glitch. Any insight would be appreciated.
