Villager trade not working right

Im trying to create a villager trade for one of my villager professions and when i try to set a price with emeralds it always ends up to be 1 emerald when i clearly set it to 15 emeralds also i tried to make a trade where the villager buys something but it showed the trade right but you just couldn't do the trade. I'm also using a Fabric Generator plugin because it worked fine with neoforge. thanks if you could help.
