Sleep alert stuck at 1 minute!

I have all the events and reminders perfectly setup, except for sleep. No matter what range I set sleep it only allows me to set it fur a total of 1 minutes. So if I set sleep to be 8:25pm, it will stop at 8: 26pm no matter what time I actually put in. It should allow me to set it from sleep time to morning time. When you first get the watch, sleep is set all the way until about 12 noon the next day, which I wanted to change. My boy is getting confused that it only tells him to sleep fur 1 minute. Please help!

figured it out. Day boundaries cause it to revert to a 1 minute jump. Set it as t 11:59pm and its great!
