Not reloading data correct and showing empty menu

Bug 1 is the empty menu showing up after removing an item from the items list of a craftable

Bug 2+3 seems like a issue with not reloading the data properly unless you reload the whole plugin after an edit.
 

Hi! Thank you. We’ve taken this into work! 

Hey Mevent, do you have any update on this. it is impossible to use as it is right now and it is super frustrating. i can even add items used for crafting without doing a massive "dance" to get it working and i'm just about had it
