I have a PDF file which is a contract, so it has been edited by multiple parties prior to my receiving it. It has both physical signatures and digital signatures.
If I open the file in Adobe Acrobat (reader and full pro version) I can't see the physical signature, just the digital. If I view in Chrome I see all the signatures.
I am guessing it is an issue with the layers not all being displayed, but I tried going to >View > Show Hide > Navigation Pane and toggling layers on and off; toggling signatures on and off, etc, to no avail.
I have attempted on multiple PC's and multiple versions of Acrobat. Since this is a shared document I need it to defaust to the correct display.
I'm not sure if this is related, but when the document is opened it attempts to auto print itself.

I don't think this has anything to do with layers. Those signatures are most likely annotations ("comments") added by some other application, which maybe didn't do a very good job of adding them. You can try exporting the comment data to an FDF file and then import it back it, or flatten the file, or even "re-fry" it by printing it to the virtual PDF printer (Windows only), to create a new, and hopefully fixed, version of it.
