'Alert Type' of 'None' results in many motion sensors
With the introduction of the 'Alert Type', when I set this to 'None', a further 13 motion sensors (20 in total) appear for my 3 Nest cameras - for face detection, etc.

When I set this to 'Motion', 7 motion sensors appear in total.

Maybe I'm not setting the 'Alert Type' correctly, but I would expect 'None' to show fewer sensors than 'Motion', not the other way around.

Please help.
