NTP client uses DHCP NTP server instead of primary server

Hi

New RB2011UAS-2HnD-IN install.
Upgraded to MikroTik to 5.21 and Routerboard to 3.00.

Enabled SNTP, set primary server IP to local NTP server, left secondary at 0.0.0.0.

SNTP client reports an active dynamic-servers IP address as 10.0.0.2, this comes from the DHCP server, but points to a broken server.
I can’t get the DHCP server fixed, sorry.

The NTP client reports that the last bad packet came from the 10.0.0.2, the bad NTP DHCP server IP.
NTP client does report the primary server as configured, but it is not using it.

How do I get the NTP client to use the specified server and ignore the dynamic server?

P.

/ip dhcp-client set [find] use-peer-ntp=no?..

Thank you, that worked.
