First of all, I live in Europe so I use metric units, so don't be confused by strange amounts. 
Let's say, I have 25kg of malt in my inventory. In a recipe I used 3.5kg. If I select "Remove from inventory" option, the amounts removed do not match amounts used in recipe - my inventory says I have 18kg. Same for hops - if I use 30g in recipe, 60g is removed from my inventory.
A bug or I do something wrong?
