When clicking on the "Item SubSets" and right-clicking on one of the "mod" tab it creates a @(mod reference) in the search bar that breaks the search option. The second, when creating a profile to save your inventory you can't delete it.

I might be doing something wrong, but if I am that means you need to change the way your mod works or create a better tutorial on how to operate it.

Sorry for late reply.

To delete inventory save - shift + right click.

FEI does not automatically update JEI search whenever it changes search field's value - you have to submit it as you would when you typed it.
