Villagers sleep outside of beds

Villagers appear to sleep on the ground at random places around their beds, sometimes even in half blocks or through them (seems to be as far as ~16 blocks). I cannot interact with them. If I find the bed they should be sleeping at and break it, they will show up besides where the bed was, then I can put the bed back and all is fine. This happens are random, and by that I mean not the same villagers on each night. Some nights everyone is on their proper places.

Seems like a visual glitch since appears that it is only a matter of them displaying in the wrong place.
