Blueprint: Deleting local variable deletes it in other functions

I have multiples functions with the same local variables in, they are in the same class Blueprint. Let’s call Function1 the first function and Function2 the second one. In each, I have a local variable called Var. Both Function1 and Function2 use Var. But, I deleted Var, only in Function1. And it deleted all calls to Var in Function2, even if I didn’t do anything for this var in Function2.
