Always on VPN NRPT rule but no policy

In the profileXML of Always ON VPN you can set a NRPT policy rule, like this.

<DomainNameInformation>
      <DomainName>.domain.com</DomainName>
      <DnsServers>10.21.12.100</DnsServers>
</DomainNameInformation>


After the VPN connects some Window 10 PC's
Get-DnsClientNrptRule returns my rule above

but

Get-DnsClientNrptPolicy returns nothing

So the NRPT rule is not applied when the VPN connects, so NRPT is not active.

I can create a policy under the GPO, that works, but that is not the same as including the policy in the VPN profile.
