Missing argument "-X" for ITL command mail-host-notification

[tectumopticum]

Describe the bug

The notification-script in /etc/icinga2/scripts has been updated but the argument "-X" is not present in the ITL-command:

./mail-host-notification.sh -h  
[...]
Optional parameters:
-X HOSTNOTES ($host.notes$)  
[...]

Expected behavior

Argument "-X" should be available by default in command "mail-host-notification"
Command-config mail-host-notification:

"-X" = "$notification_hostnotes$"
