The value of "i18n_token" is deleted when modifying alarm message through Message Pool Manager.
This is a design.
If "Activate support for internationalization" is turned on in nas probe,
UMP uses "i18n_token" to translate alarm message.
This is translation resource file that UMP uses.
If you modify original alarm message in probe side, UMP do not know the change.
To prevent inconsistency from happening, probe will remove "i18n_token" for alarm message that have been modified.
No resolution for this behavior.
Not all monitoring probes have "i18n_token" for alarm message. (for example, logmon alarm does not have "i18n_token")
For alarm message which does not have "i18n_token", UMP uses original alarm message for display.
