Plesk Warning after modifying DNS records: The DNS zone was modified.

Symptoms

A warning like this one appears after modifying DNS records for domain:

Warning: The DNS zone was modified. If you would like to apply changes in the DNS template to this zone, either click the 'Apply DNS Template Changes' button on this page or go to the Server Administration Panel > Tools & Settings > DNS Template Settings > Apply DNS Template Changes and choose the 'Apply the changes to all zones' option.

Cause

Plesk shows this message when it detects a mismatch between the domain's DNS records and the DNS template. This to inform the user they can apply the same changes to all sites, or revert them back to the defaults.

Resolution

The warning can be dismissed safely if neither of the suggested options is needed.
