Zabbix-Template-App-Docker.xml : import failed

Hello,

I was trying to setup Zabbix containers monitoring and when I imported the .xml template , I got this error on the Zabbix dashboard -> Templates : 

```

Cannot find value map "Service state" used for item prototype "Container {#HCONTAINERID} is running" of discovery rule "Running containers" on "Template App Docker - www.monitoringartist.com".

```
