sorry its me again

Today i found this nice feature that TM1 can send messages to users, but in my case it dont shows the Alias name, its just shows the CAMID Identifiier, which looks weired for non technical users.
Its it possible to send the message from my Alias that i inserted in }Clients Dimension?
I tried some ways since 30 minutes but cant find the right way...
Edit: Attached Screenshot
Thanks for you help,
love this Forum.
