LabVIEW DSC User Defined Alarm can not be deleted

[DRobin]

Hello,

i'm trying out the DSC Module Alarm Functions and encountered a problem with my User Defined Alarms.
At first it seemed to work ok and i was able to Create and Delete the User Alarms and displaying them in an Alarm Summary Column.

Right now there is 1 User Alarm stuck in the shared Variable and i just can't delete it anymore

 

 
When i try to delete it with "Clear User Defined Alarm" I get an Error ...
When i Create it, it creates it one more time and i can delete it. But the initial one is always kept. And so is the entry in the list sadly.
Is there another way to clear that shared Variable for the user defined Alarms? For my App it is called: "\\localhost\DLL_Test\UserDefinedAlarm"

Thanks for your help!
