Network machineInventoryLabels not showing after machine is registered in the cluster

[adrianharabula]

Hello! I have the following registration endpoint which specifies some $Network labels.

machineInventoryLabels:
  elemental.cattle.io/network-enp3s0-ip: ${Network/NICs/enp3s0/IPv4Address}
  elemental.cattle.io/network-ens160-ip: ${Network/NICs/ens160/IPv4Address}
  elemental.cattle.io/network-eth0-ip: ${Network/NICs/eth0/IPv4Address}
  elemental.cattle.io/network-internal-ip: ${Network/NICs/0/IPv4Address}
  elemental.cattle.io/network-secondary-ip: ${Network/NICs/1/IPv4Address}
  elemental.cattle.io/network-total-nics: ${Network/TotalNICs/}

What did you expect to happen:
Get new nodes with $Network labels. None of the labels are showing up after the machine is registered in the cluster. Example MachineInventory:

My use case for this is that I want to target machines in a pool by their IP.

Adrian.
