Villagers Won't Link To Workstations

Ive Been Trying To Build A Trading Hall But Villagers Will Not Link To Any Workstation, Even If Its Fresh. Villagers Also Won't Delink, I Set Up A Villager Breeder And Transported Villagers To my Base, To Where It Would Not Link To The Workstation I Provided, If It Helps I Moved It Via Nether Using Minecarts. I Am Unable To Provide Screenshots
