Thanks ArtC. To make sure my other options don't have effect on this codes, I shut down and restarted my SAS (v.9.2).
But after I submit the code, I still got the PDF file that have duplicate titles. I mean on the top of the page, title2, title 4 and title 5 display and, within the graph image, the three titles also show up.
At this point, since I cannot duplicate your issue, if your code is essentially the same as my test code, I have no idea what might be wrong. This is the point at which you need to start working with Tech Support.
If you open a track with Tech Support, they can look at all your code and at your output PDF and they can help you resolve this issue.
