We are using Zabbix 1.8.5. We defined a monitoring template which is assigned to all 10 hosts of a host group "Customer Foobar".
The template contains a graph "CPU usage"

How to reproduce the problem:

• Navigate to "Monitoring => Graphs"
• Select the hostgroup "Foobar"
• Select "all"
• The graph-dropdown menu now contains 10 graphs with the identical name "CPU usage"

In my opinion the dropdown should only contain one entry "CPU Usage" and if i select this dropdown 10 graphs
(one for each host in the host group) should be displayed which one single time-slider for all hosts.
This is at least a usability bug
