Asus ct8 zenwifi dedicated backhaul set to wired but showing up as wireless?

I've got the ct8 , two modules, the mesh unit on wired (into wan port). It shows as gig ethernet wired backhaul but the system in the web or mobile interface says wireless backhaul and dual mode is enabled not triband. So i think im losing throughput as a result.

On mobile i can toggle it off but it doesnt give me an option to apply.

Im running the latest firmwares.

Anyone ran into this?
