Hi David,
The response has 21 AdSchedule criterions, one for each day for three campaigns. One of the campaigns is removed, which is why you might not see the criteria corresponding to that in the AdWords UI. They will be available in the response because there is no predicate to filter out results based on campaign status in the request.
Also, I see that you now have a total of 14 AdSchedule criteria, 7 per active campaign. Are you sure you deleted the AdSchedule for Sunday successfully?
Thanks,
