The repeater section is in the part under repeater, doh!
All your problems are because you can’t see (for some reason) the proper section in the GL UI and are making (wrong) changes in Luci which then conflict with what you are trying to achieve.
As per my previous advice, reset the router or better, reload the firmware and start from scratch.
Edit: aha, I see from another post that you have done as I suggested and got it working now.
