There is a maintenance mode schedule currently applied to a device which we need to remove. However when we access the maintenance mode schedule dialog, the "current schedules" list is empty.
Spectrum 10.2
Linux OS
The list of maintenance schedules created over time has grown to be quite large, consisting of up to or perhaps exceeding a hundred schedules. The "current schedules" portion of the dialog is not populating due to the total list of available schedules being too large. 
It is recommended to delete some unused and unecessary schedules to reduce the total amount of available schedules. You can do this one of two ways. 

1. In OneClick, go to Locator > Schedules. Pull up all Schedules and delete ones you no longer need

2. go to VNMSH shell: in SpectroSERVER, log into a Bash shell and nav to <SPECROOT>/vnmsh
./show models | grep -i schedule

This will show all available schedules. Destory ones you do not want
./destroy model mh=<schedule handle>
