You have 2 options. One is to configure everything that the GL UI lets you, and then don’t touch those related things in Luci. Two is to just use the “clean” firmware version of the firmware, that is pure OpenWRT.
The issue is that the GL UI is changing things in the background, writing to configuration files directly. Luci is not seeing those changes, and will mess up configuration if you try to change conflicting settings. Generally the GL UI is much better than Luci for the settings it does have, so i would recommend you do just that, and if you need more advanced things, change those in Luci.
