Duplicate Error Messages in workspace

[Hugo12]

I have a server script that triggers an info/error message at the end. In workspace the error/info message alert is showing twice.
I have confirmed that the script is only running once. 
Any ideas on what might be causing it?

Figured it out. The Add alert notifications event mapping was being called twice in the page. removed one of them and fixed it.
