After upgrade zabbix from 2.0.10 to 2.0.11 I've got some problems with trigger's name, that use more than one values in their expressions.

Trigger example:

{mx01:system_updates[total].last(0)}>0 | {mx01:system_updates[security].last(0)}>0 | {mx01:system_updates[optional].last(0)}>0

Its name:
There are {ITEM.VALUE1} systems updates need to be installed: {ITEM.VALUE2}/{ITEM.VALUE3}

If zabbix 2.0.10 was used I received correct e-mail notification:
mx01: There are 6 systems updates need to be installed: 4/2

But after upgrade to 2.0.11 e-mail notification looks like this:
mx01: There are 6 systems updates need to be installed: UNKNOWN/UNKNOWN

And in frontend I see:
mx01: There are 6 systems updates need to be installed: 0/0

PS. More detailed information is in forum (Russian): https://www.zabbix.com/forum/showthread.php?t=44331
