repository sync problems

I've recently run into an issue where one of the Red Hat repositories didn't sync all of the packages that should be in it. When adding the Red Hat Enterprise Linux 6 Server - RH Common RPMs x86_64 6.4 repo and performing the initial sync, only 15 packages were downloaded. In the same repo for other versions, there are more than 150 packages. While working with support, they've had me disable and enable the repo to try and trigger a fresh sync, but satellite just reports there are no new packages.

Is there any way to force satellite to redownload all packages or to see why it is only downloading a few?
