You are using an extremely old version of Foreman/Katello. Support for modular repositories like appstream does not exist in that version. Modular repositories have only been supported since (iirc) Katello 4.0, which would be Foreman 2.4
I would advise you to upgrade your Foreman to a more recent release, the latest stable version is Foreman 3.4 with Katello 4.6. In case you don’t know: You cannot skip releases when updating, you have to upgrade one version at a time (so from 1.24 → 2.0 → 2.1 → etc).
