Hi there,

Thanks for reporting this. It seems that all siteadmin(super Users) are consider as admin of your Groups currently.

I have logged this issues internally and will included them on our next release version. I have made some hacks on this files .../administrator/components/com_easysocial/includes/cluster/cluster.php and it should shown correctly now. It should ignore Super Admin and will not shown Super Admin as an admin unless you set them as admin for the groups.

Please give it a check and see how it goes.
