Form 1310 is watermarked as "Don't file. Not Final"

I am completing taxes as PR for my deceased uncle and because he will receive a refund due to the second stimulus payment the Form 1310 must be sent in.  I have an IRS Tax ID so the IRS has been notified that I am PR.  But when I try to print the form, it is watermarked with "Don't File.  Form not Final".  When will it be final or how do I get rid of the watermark?

 

Thank you
