Cannot Sync Repositories

I have this issue where I cant get the + sign to enable repositories.

RHEL - 7.9
System Information
Red Hat Satellite (build: 6.7.4)
Version 6.7 © 2020 Red Hat Inc.

I have followed the installation procedure, created my manifest on the Red Hat customer portal as well as allocated subscriptions to the manifest.
Thereafter I imported the manifest under subscriptions, however, I can see some repo information, but I cannot enable any of them, I get "No repositories available.", therefore I cannot sync anything to my Satellite server.

Can anyone assist.

Regards
