Packages on repo on satellite 6.2 Web UI and satellite itself doesn't match, some kernel packages missing

I see that when I synced the following repo from UI, new packages were added, However, when I rum "yum repolist" on satellite itself, some packages are missing. For example; "yum check-update" doesn't pick kernel packages but on web UI, I see the kernel packages are there.

On Web UI:

Red Hat Enterprise Linux 7 Server RPMs x86_64 7Server --> 20111 Packages 2962 Errata

On Satellite 6 itself:

rhel-7-server-rpms/7Server/x86_64 Red Hat Enterprise Linux 7 Server (RPMs) 19,670+457
rhel-7-server-satellite-tools-6.2-rpms/x86_64 Red Hat Satellite Tools 6.2 (for RHEL 7 Server) (RPMs) 143
