Fixing the Quick Trade Button Not Working

Check Your Inventory

If the quick trade button does nothing, the most common cause is not having enough of the required input item. The mod will not perform a trade you cannot afford. Make sure the exact item the trade asks for is in your inventory in sufficient quantity, and that it is not stored in a shulker box or elsewhere the GUI cannot reach.

Check the Trade Status

A trade that is already locked, shown with a red X, cannot be performed again by any means, including the quick trade button. If the villager has been restocked and the offer is available again, the button will work.

Check the GUI

Make sure you are looking at the correct trade row. Each offer has its own quick trade button, so clicking the wrong row will attempt a different trade with different inputs. Hover over the button to confirm which trade it will run and how many times before you click.
