Graphs(Dynamic item) other than the configured host are displayed

Case:
Graphs other than the configured host are displayed.

Envriment:
ZabbixServer 5.0.29

HostSample:
tmp1
tmp2

GraphSample:
"CPU usage"

DashboardSample:
Graph(classic)
Name "default"
Refresh "interval Default (1 minute)"
Source "Graph"
Graph "tmp2: CPU usage"
Show legend "true"
Dynamic item "true"

Expected:
If a host is specified in the graph, another host will be displayed if another host is specified in the filter.
In the verification, tmp1 is specified as the filter.
The displayed graph shows "CPU usage" for "tmp1", but when clicked, "CPU usage" for "tmp2" is displayed.

However, if i click on this graph, i will see the host that originally did it.
Shouldn't this show the original host?
