noreply@ email for job application throwing an error

I am using the job applications add-on with Job Manager and the site I have is sitting on this URL https://www.essentialpersonnel.co.uk/. However it redirects from https://www.essentialpersonnel.co.uk/wp_staging (from numerous reasons).
When an application is submitted I take it the system automatically creates a noreply@ email address from the domain? But as my domain is essentialpersonnel.co.uk/wp_staging it creates an email [email protected]/wp_staging which then isn’t a valid email address which then throws an error to the user.
Any ideas how to fix this (without changing the domainor location of the site)? I can’t see a setting for altering the email so I assume it’s being created by the system?
Many THanks
