When searching packages, epoch is not shown unless a package from list is selected
Description of problem:
When searching for a package via Content -> Packages, the epoch version of a package is not shown unless a package in the list is selected, then the epoch will suddenly appear within the versions of that package inside the list.
*Version-Release number of selected component (if applicable):*6.2.14
How reproducible: 100%
Steps to Reproduce:
1. Sync rhel-7-server-rpms
2. filter by 'name = yelp' on Content -> Packages
3. Observe silly results.
Before clicking package, versions are displayed for example:
yelp-3.22.0-1.el7.x86_64 -> If we click this version for details, suddenly the list will now contain the epoch version for the package.
yelp-1:3.22.0-1.el7.x86_64 should be shown at all times.
