In Firefox pdf format, the “4” flag is displayed (instead of a checkmark); Works fine in IE and Chrome

Question

I am creating a pdf document (via ColdFusion), but when I look at the pdf rendering in Firefox, I get the number "4" where my checkmarks should be (see photo below). When I view the same pdf file in Chrome or IE, I see a checkmark and everything works fine!

I pre-populate the pdf form fields (via ColdFusion session variables), and then create the pdf using the following markup:

<cfpdfform source="82040.pdf" action="populate">
   <cfpdfformparam name="org" value="">
</cfpdfform>

Here is the resulting PDF form in Internet Explorer:

Pay attention to the correct display of the checkmark:

Here is the same form that was viewed in FireFox:

Please note that the checkbox has a “4” flag, not a checkmark.

Any help would be greatly appreciated!
