Description of problem:

When selecting a specific errata and view what hosts it's applicable to, it shows a list. When checking "Only show content hosts where the errata is currently installable in the host's Lifecycle Environment", it shows much larger list, almost all hosts. This isn't right

Installable always means applicable also. Applicable might not be installable (if not published). Errata can't be installable if it's not applicable.

So, errata which is installable for host is also applicable for host. So, applicable list should be larger than installable

Version-Release number of selected component (if applicable):

6.2

How reproducible:
Always

Steps to Reproduce:
1. Go to Content > Errata
2. Select one or more errata
3. Click apply
4. A list of host will be listed
5. Click on the checkbox "Only show content hosts where the errata is currently installable in the host's Lifecycle Environment"

6. New list will be populated with more hosts

Actual results:

I can see some host, which have installable errata but those hosts do not show up for applicable.

Expected results:

The list of the applicable host should be greater than the list of installable host, because Installable always means applicable also.
