ISSUE: Decline Submission email notification not sent to Author

I’ve encountered an issue while the submission is declined by the editor. When a decision is made by the EDITOR to decline the submission based on the reviewer feedback. It is expected to trigger an email to the Author about the decision made by the EDITOR. However in our case when a decision to decline the submission is made it triggers an email to the REVIEWER Thanking him for the Review. Even after skipping the email (from the option provided by OJS to SKIP EMAIL). The decision is recorded and stored however there is no email notification to the Author regarding the Decision.

We are using OJS 3.4.0.1

Attaching the Screen recording of the Issue with steps below:

Thank You,

Best Regards,
