Bizarre Wired Backhaul Observation (X55Pro x 3)

My fiber service was down for a couple days. During that service interruption, I used a 5G dedicated hotspot as my backup WAN port. FWIW, OpenWRT router. Why did the Deco app finally show my satellites were on wired backhaul vs wireless?

As soon as our fiber service was restored, I shut down the temp WAN ports, (re)enabled my WAN port used by the fiber, and now inside the deco app, my satellites are again showing wireless backhaul. SO WEIRD!!

The main difference between the regular WAN vs the temp WAN:

Regular WAN is a static IP address. Temp WAN were setup as DHCP clients.
