This isn't the same as the cited duplicate. For my example I had a librarian with a mending book for 22 emeralds locked in (I had traded with the librarian) I moved this villager's lectern inside a house and went to trade with the same villager and found that his experience level remained the same but his trade switched from the mending book for 22 emeralds to a Infinity book for 14 emeralds. This has never happened before to me.
My wife had a similar issue with a villager who had a luck of the sea 3 book locked in and when she went back to trade with this villager again the trade switched from luck of the sea 3 book to a bookshelf. This all happened within the same few hours on our server.
Umija5859M I can see that similarity now that you put it that way. In my situation there were not any other available job blocks.
Hopefully a solution to this issue is found and resolved soon.
Thank you.
