Villagers not linking to work stations

I dont know why, but I cant get villagers to link to work stations. These are villagers I have bread myself. I had them set up in an iron farm in the 1.16.2 update and my iron farm worked like a dream. Ever since the 1.16.4 update, iron golems have stopped spawning. I have double checked, and all of the villagers are infact still there. So I tried breeding new villagers elsewhere in my friends realm and None of the new villagers I breed are linking to workstations. I have tried every way I can possibly think of to get them to link to a work station, but they wont.

My friends on this same realm are playing on pc and able to get their villagers to work just fine. But for some reason, me playing on the Nintendo Switch, it doesnt allow this to work.
