Steps to reproduce:

1. Create a trigger expression for number of running processes for Linux. Example using average trigger function and value greater than 30 --> _ {[FQDN_OR_IP_HOST:proc.num[,,run]|https://zabbix.eng.citrite.net/items.php?form=update&itemid=397217].*avg(*5m*)*}

   >30_.

2. Create a Zabbix Action and include the Zabbix Macro {ITEM.VALUE1}.
3. When the trigger is fired the item value is incorrectly displayed.

This happens rarely but believe this might either be using the wrong macro or a potential bug.

I wanted to get clarity on this and whether this has been seen before.

I am using Zabbix version 4.0.15 on Debian 9 OS with partitioned (pg_partman) PostgreSQL v11.4 database.

Result: The Zabbix Item Value in the Action displays a wrong value; happens rarely. See attached screenshots.
Expected: To see the proper item value when the trigger fires.
