Annoying trigger bug when changing variable

Hello, I'm not sure where to report bugs these days so am going to throw it out here.  This is something that is driving me a little nuts.

I have a bunch of triggers to do some basic math calculations - multiply, divide etc.  I want to reuse these triggers within the same course but just change the variable names. When I try to change the variable names in the trigger - Storyline changes the operator to Add. If I am not paying close attention and remember to change the operator back to what it was originally, then my calculations set screwed up. It is a pain having to reset these because a simple math function has a ton of triggers.

Has anyone else found this issue?
