    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).
