When you say you go into settings and remove are you referring to deleting the schedules or are you saying you are removing the devices from the app?  If you are removing the devices but not fully resetting them they will keep the programing i.e. the schedules at appear to be configured.  You would want to delete the schedule if your not already.  There is no way for the plugs to "learn" a schedule.   Unless the plugs are part of a scene and that there is a smart actions to schedule the scene to go off.  

If you are removing the schedule what I would suggest is resetting the cloud account's (your sign in) password.

Yes, I deleted each of the on/off commands for each device. Also have no scenes programed. The same programming comes back as if someone is logging in my account and programming just the same two devices. 

@Marspinball 

As this is  single access system have you tried changing your account password?

@Carl 

No not yet. I'll give it a try. 

Thanks Martin
