Variable Addition Doubling?

I have it in my mod where when a player collects item 1 (example name), a global variable increases by one, and when item 2 (another example name) is picked up, that same variable is increased by five. That SHOULD be happening. However, MCreator doubles the added values for some reason (item 1 adds two to the variable, and item 2 adds ten to the variable). I have to half the added amount so that it gets doubled into the correct value, but every now and then it still adds by the halved amount.
