Problem similar to that described by me in ZBX-2250, only with the macro {ITEM.VALUE}
The problem lies in the fact that the function does not work when using a macro ValueMapped {ITEM.VALUE} in the description of the trigger.
For the macro {ITEM.LASTVALUE}, at least in the menu Monitoring -> Events and Monitoring -> Triggers, data are substituted correctly.

For the macro {ITEM.VALUE} data correctly substituted for notification via e-mail.
At the same time in Monitoring -> Events and Monitoring -> Triggers using ValueMapped, the data is displayed without any conversion.
