Issue getting DHCP associated with rack controller

I’m trying to configure a subnet for DHCP and no matter what I do, the subnet never thinks it is associated with a rack controller. What I mean by that is this:

➜  ~ sudo /snap/bin/maas potato vlan update 5 untagged dhcp_on=True primary_rack=lst-maas -k                    
Machine-readable output follows:
    "vid": 0,
    "mtu": 1500,
    "dhcp_on": true,
    "external_dhcp": null,
    "relay_vlan": null,
    "fabric_id": 5,
    "secondary_rack": null,
    "space": "undefined",
    "name": "untagged",
    "fabric": "k8s-fabric",
    "primary_rack": "eysnfp",
    "id": 7,
    "resource_uri": "/MAAS/api/2.0/vlans/7/"

As you can see, it says success. If I go to the vlan, rack controller has a value and status says enabled. But If I go to the subnet and try to map subnet I get:
So I’m just stumped what I’m doing wrong. This is a single host deployment, on a VM that does not exist in the same subnet as what I’m trying to serve up. Is that the issue here?
