Librarian Trading Glitches

Just updated to 1.14.3.  Playing a world started under 1.14.1.

 

Librarian trading windows either do not open, or flash open and immediately close. n This only happens with librarians.  Also, after about sixty attempts to keep a trade window open, I have three stacks of wheat and four stacks of wheat seeds in my inventory, that were not there before trying to trade.
