Hi there,

Sorry for any inconvenience caused.

Actually, the reason why it does not shown numbers on that view is because we enforce this not to be shown on that particular view. If you wanted to shown its counter, you need to apply language strings below on your language files/ language overrides.

COM_EASYSOCIAL_GROUPS_MEMBERS_PLURAL="%1$s Members"
COM_EASYSOCIAL_GROUPS_MEMBERS_SINGULAR="%1$s Member"

And for the second points, if you check using Protostar(Default Joomla Template), it will shown you those icons(as stated on my above reply). So if you wanted to show those icons on your site, you can apply css codes below.
[gist type="css"]
.com_easysocial #es .es-nav-pills .o-nav__link .fa {
display: inherit !important;
}
[/gist]

Hope this help you understand.
