Heartbeat list of host help

Ok So i got the name to show up in Kibana the way i wanted it to show with this yml config

type: icmp
name: icmp
enabled: true
schedule: '@every 2m'

List of hosts to ping

hosts: host1
name: host1

however when i added an additional host like so

type: icmp
name: icmp
enabled: true
schedule: '@every 2m'

List of hosts to ping

hosts: host1
name: host1
hosts: "x.x.x.x"
name: "host2"

it looks like it stop pinging host 1 and now only pings "x.x.x.x"

**it only shows the last host that was added. **

***for example my most recent config file had "x.x.x.x" "y.y.y.y" and "z.z.z.z" now it only show 1 ping top z.z.z.z ***

I am going to use this discussion to add notes for others in the future that may have this similar issue.
