Locks and smoke Co2 sensors disappear from ring app

Today I noticed that my two of my z wave accessories are missing from the ring app. My Schlage door locks and my first alert smoke and co2 sensors were gone. My locks came back but my smoke and co/ have not and under professional monitoring it shows none for smoke and co2 sensors being monitored. All have fresh batteries. This happens from time to time and is not great especially is you are away. iOS 17.1.1 and latest ring app on an eero pro wifi system.
