Hi kihomachelpdesk,
TSN is correct, this is not tech support, but in this one case you've have gotten a hold of Adobe anyways.
The name that you see in the textual portion of the digital signature appearance (the right half of the signature field) is the value of the CN (common name) entry in the Subject extension of the digital ID used to create the digital signature. You need to procure for Ms. Leonard a digital ID from Symantec with a less frightening set of entries in the Subject name. Note that the OU (organizational unit) also says "Persona Not Validated" along with the CN entry. One of the tenets of using a "trusted third-party" to supply the digital ID is it's their job it to have vetted the identity of the end-user to whom they are issuing the digital ID. That way the document recipient (who must physically trust the Symantec Root CA certificate in order for the signature to be valid) is assured the signer is who they say they are (it's known as non-repudiation). My guess is Ms. Leonard obtained a test (or sample) digital ID form Symantec and since Symantec gives those away they don't bother with the identity vetting procedure like they do with digital IDs that are paid for. Since they aren't doing any identity verification they add the "Persona Not Validated" text so the document recipient isn't fooled into the believing the signer is someone that they are not.
As an aside, you can also make the graphics portion of the signature appearance (the left half of the signature field) look a bit better if you make the background of the signature appearance file transparent (aka removing all background opacity). That way the background won't obliterate the trefoil logo. And if you really want to get fancy you can replace the trefoil with your own company logo.
