Error on changing email address of customer in Plesk: Incorrect DNS zone parameters were specified.('displayName' = '', 'name' = '')

Applicable to:

A customer with a subscription was created in Plesk when the component BIND DNS server was not installed.
After installing BIND DNS server, the following error is shown upon changing the email address of that customer in Plesk in Customers > John Doe > Edit Contact Info:

The customer's email address is actually changed.
