Missing menu item "List Cloudmin Managed Systems"

We’re running 9.3.kvm Pro on a CentOS 7.4.1708 host system. Our virtual servers are not running virtualmin, only webmin, and we don’t run virtualmin on the host.

Recently, we noticed we are no longer able to list our managed systems. There is no longer a link on the left menu to list Cloudmin Managed Systems.

When we click on Cloudmin > System Information > Cloudmin Managed Systems, we see the correct number of Managed Systems, but we can’t find a way to get to the usual page where we can perform actions on individual systems such as reboot, check packages, execute commands, etc.

I don’t see any errors regarding this in /var/webmin/miniserv.error

Thanks for any guidance…
