Check Box “On” Question

Thanks for your quick replies to questions!

I have a question about the Check Boxes… when I map the fields, this is the syntax created:
<label>A</label> [checkbox pdf-field-all-a-QQ “On”]

When I view the form online, it shows the following:
A On
B On

so it contains the word “On” on the form… and I don’t want that to show. But if I remove the “On”, then the PDF is not filled in properly.

This is the link to my Form:

I’m still going through and building it. Thanks!
