NTP Stratum incorrect

I have a catalyst 9300 switch running 17.12.04.  When NTP is configured, it can see its two sources. But it incorrectly lists them as being stratum 16. eg;

#sh ntp assoc

address ref clock st when poll reach delay offset disp
~10.70.240.40 .TIME. 16 - 64 0 0.000 0.000 15937.
~192.168.238.79 .TIME. 16 - 64 0 0.000 0.000 15937.
* sys.peer, # selected, + candidate, - outlyer, x falseticker, ~ configured

Other NTP clients on the network see these sources as Stratum 6 and 1. Why might it be assigning an incorrect stratum and is there way i can override it?

Issue was the switch is communicating through an out of band interface using vrf vrf-mgmt.   I needed to factor that into the ntp config.
