Remove from Inventory when short zeros out all linventory

I'm not sure if this is a setting or just a bug but I found an issue in the inventory system.

I built a recipe that had multiple hop additions and the total needed was less than my current stock. When I clicked "Remove from Inventory" the system said that I either had no stock or not enough stock and did I want to continue. I clicked "No" but when I went back to my inventory list the amount of hops that I had in the inventory was now zero even though they should not have been removed.

I am using version 2.1.02 on a Mac

Are you certain the Hop in the recipe was the exact same Hop in the Inventory? 

It's more common error with grains, but for ex, you may have a Citra hop at 10AA% and a second Citra at 11AA% in inventory, and the wrong one is in the recipe. 

When I re-do a recipe, I make myself go through all the grains and select from what is current in my inventory to ensure I'm pulling from current stock/items.
