I updated my antigu map to 1.20.0.01, and villagers were simply taking "wrong" professions, they were taking profession but not the professions that I put 

I don't know if it's a problem with my map, I don't know if there was a conflict because the map I was playing was from 1.14 and I updated it and everything looked fine, I also had other villagers on the map and they disappeared even if they were renamed with a label 

thank you mojang and hope it works
