I've noticed that when setting up Wireguard interfaces and peers in LuCI, that if an Interface is deleted, it leaves the peer config settings in /etc/config/network. Has anyone else exprienced this?
Yes, I had the same issue. Would probably have to be fixed in the "luci-proto-wireguard" package I would say. You can circumvent the issue by simply opening the file in a text editor like vi and deleting the configuration lines manually. Afterwards, reload the new network settings by using /etc/init.d/network reload
