In the Interface, navigate to: *Content > Errata > click on any Errata ID > Repositories tab*
In the filter bar Area (under "Repositories containing <erratum_id>") it says "There are no Content Views in this Environment" and the drop down filter for Content Views is greyed out.
This is true for every erratum I looked at and irrespective of the Lifecycle Environment that is selected.
When I check under Content Views, various versions of the views containing the relevant repositories are promoted to various Lifecycle Environments.
I have seen this affect both SUSE errata and CentOS errata on different Foreman/Katello installations. (Katello versions 3.4.5 and 188.8.131.52).
