Singlestat not refreshed

I am using grafana V5.2.3 on Centos V7 connected to zabbix.
I have both graph and singlestat panel for one item.
When the item change, graph will be refreshed without problem but in singlestat the story is different.
Singlestat value and even background color is not refreshed.
I checked spark line for my singlestat , spark lines refereshed but tha value is not.
