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.

In workspace, I have embedded a playbook component. That playbook record generator is generating a record in table. duplicate record validation is there which is implemented via Business rule. Business Rule is showing an error message if that record is duplicate. That error message is appearing twice in workspace. How can I stop that message coming twice. It should appear only once. Please help me to fix it.
