Previous cured converted villagers will not link to a job block after breaking and replacing block

 I converted villagers before the new update. I was able to trade with my librarians, brake lecterns, move lecterns and the villagers will relink to a lectern then reset again. Worked perfectly. Now after the new update, I moved the lecterns and none of my librarians will link on the job block. (No green particles and no red particles floating around heads). They will link to a bed, but not 1 of the 12 lecterns. This is a new problem. I have never experienced this issue before.
