Description

Tested this on two worlds, the one that's having trouble is my survival world I have with friends. Whenever I interact with a vendor to buy something it does it twice.
Example: I have a vendor that sells a piece of coal for one spur. I click on the vendor with my spurs and it takes two spurs but still gives me two coal even though it's supposed to be one coal for one spur. This happens no matter what the values are, doing the transaction twice. If there was only one piece of coal available in the vendor, it will still just charge one spur for it, which is why I assume it's just doing the interaction twice for some reason.

I then made a creative world to test it out there and it worked as usual, only doing the interaction once.

Figured out the issue! Turns out if I had an iron shield in my offhand for some reason it did the interaction twice, but if I have nothing in my offhand it works as intended. Just wanted to follow up on this report to make sure I didn't make y'all guess with it.
