Error when adding schedules

There was an error adding the schedule, already exists DB error: Incorrect integer value: '' for column 'maxload' at row 1

Any ideas? This is when trying to add a schedule?

Any schedule? Can you tell me what you entered? I couldn’t duplicate this when someone reported it before
