saving network discovery rule remove from all actions (Actions->Discovery) at "Discovery check" defined in this network discovery rule

Hi,

I create new network discovery rule "my test" with check :

Zabbix agent "system.sw.os[name]"

Then, define new action :

Discovery check = my test: Zabbix agent "system.sw.os[name]"
Received value = 1

Now, once I just open network discovery rule "my test" and click on SAVE
my action will be modified and "Discovery check" will be deleted, I will see only :

Received value = 1

This start happened after upgrade to v2.2.4

Let me know if you need more details from me.

Thanks
