Functions in Messagetemplates are all Resolved to {ITEM.VALUE1}

Steps to reproduce:

Every Item Funktion in Message Templates is resoved to the {item.lastvalue} Value.

e.g. Alarm for Printer Toner below 20%... the Toner Value is 19

In the Message I have something like:

Toner-Value: {item.lastvalue} 

Modell: {?last(/

/deviceModel)}

In the Message I recive

Toner-Value: 19

Modell: 19

-> in the Message, the Funktion it is not Resolve to "HP Laserjet", it is resolved as "19"... the Value of the Item that Trigger

Expected:

For Funktion of  Host Inventory Field it work.
