Renaming on Save - Reader XI

Hello

When I use fill and sign in Adobe Reader XI on an existing pdf when I close the doc I am prompted to ‘save as’ the document as a seperate document instead of updating the existing document.

I believe this is being caused by Adobe adding in the word ‘-signed‘ into the file name so adobe is detecting another document.

I have disabled Protected View and various other certificate settings but no matter what the file name gets changed on the ‘save as’ window.

I have spent hours researching this to no success.

I just want to sign the same doc without being prompted to save it as a seperate document.
