I called Proseries to get the solution.  It does not work when send it from the homebase. Assuming it was signed the first go around.  I had to send it from the tool bar "eSignature > Request". That worked. 

The issue is, if you have an 8879 already signed and you need to re-do it, the homebase does not work; even after you void it. It continues to send out the original 8879.  But going to the tool bar as I mentioned above, works perfectly.
