Your question is translated to

> It won’t let me create a certified copy after signing digitally.

If the translation is correct:

A certified copy is a copy signed with a certification signature. 

A certification signature, aka author signature, is a special type of digital signature that allows the signer to set a certain MDP (modification detection and prevention) level that determines which modifications shall be allowed to the document. 

According to the PDF specification, a certification signature must be the first signature of a document. 

Thus, you cannot apply a certification signature to a PDF that already is digitally signed (at least not without flattening or otherwise removing the pre-existing digital signature).
