While playing on a Minecraft 1.14.1 vanilla server, I ran into an issue where I can't enchant my fishing rod. It isn't disabled or anything because I own the server. An enchantment did pop up once, but it wasn't ideal so I enchanted a book and put my fishing rod back in and I still can't.
I tried:
Waiting,
Relogging, and
Restarting my PC
Nothing seems to be working though, I did try it in previous versions where it has worked as expected.
The described behavior cannot be reproduced on 1.15 Pre-release 2
