I have the same issue, villagers lose workstation sync and bed sync.
I had them in a one floor trading hub configuration, sorting them in shops by job. So four farmers would be in one shop, with four beds and four composters.
However, when adding new villagers in a new shop near them, some of them would stay awake at night having exchanged beds with a villager of another shop.
Also, when I decided to add another shop of four farmers, they also seemed to exchange the composters, preventing them from restocking.
This makes impossible to set up shops, or to organize the villagers in anyway to make trading easier.
Just to clarify, I used the farmers in the example, but all jobs have the same issue.
