private IP instead of public in DNS settings when migrating to server with private IP

I guess this is easy to confirm, and it looks like a bug (I can't think of it as a feature).

So, I have a plesk virtual server (12.5) with a private IP and the public IP configured in IP addresses.

Now I'm migrating a domain from another plesk (12.5) server to the above server and the DNS settings that are set up are showing the private address instead of the public! It says for example in DNS settings that the A record for my domain is 172.31.1.100, which is the private IP of my server....
