I have been trying to understand what happens when we do this:
yum --enablerepo=smetest update e-smith-backup
on a 7.3 server. I don't have a way to test as all my servers are production at this time and I use DAR2 for backup. I see a couple of possibilities.
1. Backup with DAR-panel gets updated and works correctly.
2. The original Backup or Restore-panel gets updated with the functionality of Backup with DAR.
If option #2 happens it will not fix the unsorted menu problem as the old panel stays there. You would need to check that the function you needed existed in the Backup or Restore panel and then possibly remove the Backup with DAR contrib to fix the unsorted mess. I raised a question in the bug here
http://bugs.contribs.org/show_bug.cgi?id=4229 about getting Backup with DAR back into the contribs repo for those using 7.3 so the single command would update that panel along with the rest of the contribs. The response was negative. I think you should
raise a new bug on this specific issue as I do not think the current situation is recoverable without removing of the current contrib from your server.
WARNING this is another of my untested assumptions
