Describe the Bug

WAN1 is my default WAN connection via SFP+.
WAN2 is my backup WAN (failover only), via a 4G modem

The setup dialog let's me choose between WAN1 (RJ45) and WAN2 (SFP+). I have to select WAN2, because the SFP+ is my default WAN connection. It's a bit confusing that this is labeled WAN2, while the Unifi interface calls it WAN1.
The system is working flawlessly, so rather than a bug, this is a recommendation to update the labels in the setup dialog.

Expected Behavior

Show the SFP+ WAN as WAN1, instead of WAN2 to be compatible with the naming in the Unifi admin interface.
