You're right.Probably best to reset the app by clearing its data then force stop it.
Yeah sorry there wasn't an easier way but glad I could help.You're right.
Clearing the Clock's Cache & Storage was the only way I found that was able to remove the Bedtime Schedule.
Only hiccup was that I had to reset my alarms & some settings afterwards. There should be a better way to remove Bedtime & other schedules, but ... this is Google.
Thank you everyone.
