It's so much less obvious that I'm going to ask you to explain the difference to me because for the life of me I can't see it?

Okay I even made the mistake here.

It happens when you put in ".21", not when you put in "0.21". If you omit the leading "0" it might drop the leading "." too.

That makes more sense, thank you for the update.
