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

Thanks for clarifying here Ofer and my apologies for misunderstanding. These older threads I try to just deal with the question as written in the most recent reply as sometimes they don't connect. 

Within Storyline are you using Storyline 1 or Storyline 2? Within Storyline 2, I know a few users shared that if they were renaming the variable it would update to Zero - so perhaps that is how you're seeing it as well? Also clicking inside the numeric entry to update the formatting has changed it to Zero before - so you'll want to ensure you're clicking the lines of the text box.
