Ok I figured this one out.

When you add a network to an org it creates the edge gateway for you but sets:

<BackwardCompatibilityMode>true</BackwardCompatibilityMode>

You need to update this to:

<BackwardCompatibilityMode>false</BackwardCompatibilityMode>

Once you do this you will see that your Edge Gateway now has a check in the Multi-Interface Mode column.
