Question:
Why are we seeing devices being discovered and immediately placed into maintenance
 
Answer:
You may see device being discovered into the Spectrum topology without your input if you have set from the VNM model > Information tab > Trap based continuous discovery sub view :

Unmanaged trap handling set to “enabled”

New devices in Maintenance to “yes”

This means that when traps are received from devices not already discovered in Spectrum they will be discovered / modeled and then immediately placed into maintenance mode.
