BUG: interface config not cleared when using initial install menu to change it

[skatopn]

I installed 24.7 on an Intel NUC. I like to assign interface 'xxx0' to 'outside' and 'xxx1' to 'inside', but the default is the opposite. After I installed, I chose to assign the interfaces and LAN IP address according to my preference, however, I could not ping the inbound gateway router. Not even any ARP entries. After some playing around I decided to go back to the default interface assignment and see if that worked. After going through the menu options again to choose 'igc0' as LAN and 'igc1' as WAN and assign VLAN 2 to the WAN and give the LAN the inside IP address (which will be my GW IP outbound), ifconfig showed me that both LAN and WAN have a VLAN2 subinterface and the same IP address is on both WAN and LAN (parent).

I found this reddit post which appears to be this exact issue in 23.x:

Attached is the output from ifconfig.

Anyone know anything about this behaviour, and a fix for it?
