Proxmox and Unifi VLAN Identification

I have a Unifi Cloud Gateway with a Unifi switch, with a Proxmox VLAN setup for management at 192.168.8.0/24 (VLAN8). On the switch, I have VLAN8 set as the native untagged VLAN passing to my two Proxmox nodes. I am passing a few VLANs as tagged through to Proxmox for LXC and VMs. In Proxmox VE, I have vmbr0, vlan aware, set with static IPs in VLAN8. I also have a Linux VLAN setup in Proxmox for communication with my NAS for storage; VLAN7 - 192.168.7.0/24, no gateway set, just a static IP.

My issue is that Proxmox is identifying itself as being part of VLAN7 (storage) in my Unifi console. This should not be the case, that VLAN is just for storage. Proxmox should be identifying itself in the Proxmox VLAN8.

Is my vmbr0 configuration correct with my Proxmox management IP being set on that interface? Or should it be set on a Linux VLAN/bridge in the network config as a separate interface? Does vmbr0 require an IP address to be set on the interface no matter what?

What am I missing or what do I have incorrect?
