Form | Supervisor is getting the notification on submission

Content

Hi 

We are using the form for some documentation When user submits the form, a notification is sent to the supervisor/manager.  We have not enabled the supervisor notification on submission in the work flow..  Ideally no notification should be sent to the user

What could be the reason of this sending notification

Thanks in advance
