I did try that, but the result was the same.  The code G 1099-R is showing up properly on Line 4a, but not 4b.  I was wondering if this was the unintended result of a recent update (like today's), but I'm guessing we would be hearing more about it, if that were the case.  I even closed Proseries and re-opened it before re-entering the 1099-R.  I've perused the bottom portion of the form and nothing appears to be out of place, no extra entries or checkboxes, etc.  I'm puzzled.
