V2 and Pan Cameras not appearing in list of available devices for Cam Plus

I purchased 9 Cam Plus licenses and want to assign some of those licenses to my V2 Cameras, but they do not appear in the available devices list. My V3 and outside cameras appear in the list (not sure why the outside cameras appear as that would be a drain on the battery).

Is there some method of getting them added? I looked at the Cam Plus setup guide, but that is telling me to do exactly what I am trying to do, but the cameras are not there.

Edit: My pan camera is also missing from the available devices

@eohalloran
Can you tell me what firmware your v2 cameras are runing?

All are at 4.28.4.41
