How to remove an initial value (0) from a "Numeric Entry" field

I had this happen to me as well. Looking over the history of this issue, I found out why. Alyssa Gomez, 2 years ago: "This is happening because there is a bug in Storyline 360 where when you rename a numeric variable, the entry field and the variable reference display a 0 instead of the default blank."

My solution is to return the numeric variable to the input field, then create a second trigger that sets my variable to the numeric variable when the input field looses focus.
