Remote hosts' reports not uploaded to the Reports tab of the Foreman

OpenSCAP scans for remote hosts are successfully, but reports don not show on Foreman’s Reports tab.

Expected outcome:
After a successful scan I expect the reports to show on Foreman’s Reports tab, be it for the foreman server or for the remote hosts.

Foreman and Proxy versions:

Foreman and Proxy plugin versions:

Distribution and version:
Foreman Server: CentOS Linux release 7.9.2009 (Core)
1st Remote Foreman Client: CentOS Linux release 7.9.2009 (Core)
2nd Remote Foreman Client: Red Hat Enterprise Linux Server release 7.9 (Maipo)

Other relevant data:
After viewing the full scan report of the 3 hosts from the foreman server dashoboard. The reports show the scan report for the foreman server only and not the remote clients. Even though the scan for all 3 hosts together was a success

I need help to have reports uploaded into main foreman-proxy and be able to view them
