Some leap 15.3 update channels missing?

Hi, I've just used: `spacewalk-common-channels -u admin -p pass -k unlimited -a x86_64 'opensuse_leap15_3*'` to create the Leap 15.3 channels in Uyuni (2021.05). However if I compare to a Leap 15.3 client it did not import these repos: repo-backports-update -  http://download.opensuse.org/update/leap/15.3/backports/ repo-sle-update - http://download.opensuse.org/update/leap/15.3/sle/ Is that intentional or should I create these channels/repos manually? Thanks David
