Native VLAN not shown for trunk

Hi

I am running DNA Center Version 2.3.3.7-72328 and have just noticed an odd thing with native VLANs,

When you show the switch front panel view in Inventory and hover over a port one of the fields in teh box that pops up is "native VLAN".

For normal access ports this is populated with the correct VLAN (i.e. whatever "switch-port access vlan X" is set to. The same for trunks between two Cat 9K switches (though all of these are set to native VLAN 1) on this LAN.

However we have some edge trunks going to Meraki MX67s with native VLAN set to 2001 and nothing is displayed in the native VLAN field apart from "-".

Is this a bug?

The port config is:

interface GigabitEthernet1/0/32
 description Primary Meraki_MX67_Port2
 switchport trunk native vlan 2001
 switchport trunk allowed vlan 2001-2005
 switchport mode trunk
 spanning-tree portfast trunk
 spanning-tree bpduguard enable
end

I did some more testing. This is the same with a Cat9500 to Cat9300 trunk. It will display the native VLAN id if its 1 but if its any other then it just displays "-". Smells like a bug.
