Chime Pro as seperate device in 2.4 and 5gHz using eero

I use eero for my wifi. About a month ago eero started showing my Chime Pro as 2 separate devices each with a unique MAC address with one being the 2.5gHZ and the other the 5gHz. For some reason it stayed connected only to the 2.4ghz signal. I reset it and now it stays on 5Ghz signal but seems like it is trying to switch at times to the 2.4 ghz. It intermittently shows offline as both a 2.4 and 5 device then reconnects after a minute back to 5gHz only. It is also emitting the temporary wifi connect signal as I see it in listed wifi networks on a PC program I use to check wifi networks in my neighborhood. Rebooted eero and restarted chime pro several times with same results. I think my chime pro is defective.
