Cam V3 Spotlight Troubles

The first spotlight I installed on my first V3 works ok. So I don’t understand why neither of the two additional spotlights I ordered for a couple of additional V3s work. One refuses to be recognized by the app. The other blinks constantly but is set on “motion activated” and “fixed” duration. The latter is running the latest firmware and attached to a cam running the latest firmware via the latest updated version of the app. Can anyone surmise what’s going on here:

This behavior was occurring before and in the absence of any motion in the field of the cam’s vision long before I stepped in front of the cam to take that video.
