Repos missing from Default Organization View

Hosts which have the Default Organization View assigned lost theire repos from rhel-8.
Assigning any other content view brings the repos back.
Only repos from subscription are affected.

ContentView 84 assigned (RHEL 8.4 incl. e4s)
subscription-manager repos shows (amongst others)
repository-ID: rhel-8-for-x86_64-appstream-rpms
Repository-Name: Red Hat Enterprise Linux 8 for x86_64 - AppStream (RPMs)
Repository-URL: https://foreman.*******/pulp/content/RC0/Library/84/content/dist/rhel8/8.4/x86_64/appstream/os
Aktiviert: 1

As soon as content view Default Organization View is assigned the repo is gone.
subscription-manager repos doesn´t show it anymore.

Any idea how to debug this?

Expected outcome:
In the Default Organization View all repos should be available.

Foreman and Proxy versions:
(Upgraded from 3.2 where the problem started)

Foreman and Proxy plugin versions:
foreman-tasks 6.0.2
foreman_ansible 7.1.2
foreman_remote_execution 7.1.1
katello 4.5.0

Distribution and version:

Other relevant data:
Simple Content Access ist enabled

Does this command show anything issued on the host?
subscription-manager list --available
and what about this one:
subscription-manager list --consumed

subscription-manager list --available
shows all RedHat products from the pool (including RHEL8)

subscription-manager list --consumed
returns that no pool is consumed (which is expected sind Simple Content Access is enabled)

Anyhow I could solve this myself over the weekend.
The solution was to go to “Red Hat Repositories”. Disable the repos which had this problem and
enable them again. After that the repos show up in the “Default Organization View”.
