villager doesnt choose profession from a certain block, but not due to distance

In my friend's realm (in which I play) we have a tower where we place the villagers to exchange. The tower has 6 floors and each floor has 2 sections, for example, on the first floor there are farmers and shepherds, on the second there are butchers and fishermen, etc. The problem appeared recently, when I tried to put a librarian on the left side of the tower, since he didnt choose a profession, however, if I put a worktable on the right side, he did choose. This happens to all new villagers, except those who already had an assigned table. In the image, the scaffolding shows where the problem begins. Scaffolding to the left, tables doesnt work, scaffolding to the right, works just fine
