Hi. I don't quite understand why certain hosts in a group are not showing up on the monitoring overview, yet when I click on configuration of hosts and select the appropriate group, they are all listed there and are being monitored? 
I'm using a custom template I made which is a simple check (ping)
I'm using Zabbix 1.6
