Villagers Mixing Up Professions. Gaining New Ones

I have an open villager trading hall with pretty much all master villagers, and a couple professionless ones and babies. I decided to move around some workstations. So I broke all of them, and shifted them around. When I put them back, the villagers that already had the matching profession of the workstation weren't prioritized to choose the workstation. So for example, if I have a master farmer and a villager without a job in a room, and I put down a composter, the master farmer should be prioritized to choose the workstation first. But that's not happening. I'm pretty sure this worked fine in previous versions, such as 1.15.

Is this even a bug? If it isn't, I won't ever work with villagers again. This makes villagers almost useless because the ones that are already leveled up won't get a workstation, and won't be able to restock.

I'm currently playing in 20w15a, but this bug happened before this. Still in 1.16 though.
