[SOLVED] Possible 18.06.0 bug - selecting interface type

All,

I have an IPIP interface that I configure using Unmanaged (interface: tunl0). When I change this interface to Static Address, or vice versa, it improperly selects a Wireguard interface as the option ifname (interface: azire_wireguard) and save/tmp-rollback the wrong interface name.

Any ideas?

Current workaround: manually editing /etc/config/network

EDIT: DISREGARD. Physical interface tunl0 is not defined anywhere else in /etc/network/config (hence why I use "unmanaged").
