Excluded repositories appearing as outdated packages in YUM Manager

I was getting daily notifications from yum's update cron job due to 404's caused by outdated repositories missing some file or another. So I added the offending repositories to the exclude list in:

Code: [Select]

#/etc/yum/pluginconf.d/fastestmirror.conf
exclude=epel.gtdinternet.com,espejito.fder.edu.uy,mirror.espoch.edu.ec,mirror.upb.edu.co,mirror.cedia.org.ec

But now the excluded repositories appear as out of date packages in the yum manager:


So now I'm getting daily notifications about outdated packages despite being up to date.
Is there any way to stop excluded repositories from appearing as outdated packages?
