Hey Jeremy, I really appreciate your help, but I think that I'm probably not explaining myself correctly. The problem is not in the form's label but in the input placeholder.
That being the text that appears within the input before typing anything into the field. It doesn't have a space between the Field's name and the required caption.
Please see this:

Look at the first field "First Name", where the placeholder appears as:
First Name(required)
... all glued together. That's what I'm referring to. Hope you can fix that tiny minuscule annoying detail.
