Unable to update Fedora after upgrading from Fedora17 to Fedora18

I have just upgraded to fedora 18 from 17 using fedup tool. The upgradation process succeeded and I can feel the new desktop appearance of fedora18.

when I tried to update using yum update. I can see that the fedora17 files are not removed completely and they are also listed below the files to be updated list.

I have attached the standard output of the terminal update window with the thread.

could anyone help me out to fix it ? :wall:

Are the files truly redundant to fedora 18 files? Maybe 18 runs partly on 17 files?
