Missing repos on newly subscribed Hosts

Newly subscribed Hosts do not get all repositories of a specific Content View, while already registered ones do not have this problem. All repos are activated/synced and work if I use them manually.

Expected outcome:
Enabled repos should be availible as intended
Foreman and Proxy versions:
Foreman and Proxy plugin versions:
Distribution and version:
CentOS Linux release 7.9.2009 (Core)

Other relevant data:

Only 4/8 repositories are availible/visible in my local .repo file. Deleting the old subscription/caches and force subscribing the server doesn’t help either. I don’t get any Error Messages or Warnings.

The only way to get my repositories enabled is by creating a new repository, sync it, add it to the content view and creating a new version. Doing this for every repository would be very time consuming.

Imo there’s a problem somewhere between katello and the subscription manager.
