After adding manager's to queue, unable to send notifications to different emails. Please add back advanced settings under notifications

After adding managers to a queue it removes the ability to go to the advanced settings under notifications and change each notification's email.

We use salesforce and create cases from email's, once I added managers to the queue it removed my exisiting notification emails and replaced them with the managers emails and I'm unable to change this. It's frustrating because now my only option to fix this is to clone an existing queue

Please either allow me to remove manager's and/or add the advanced settings under notifications once manager's are selected
