I am having trouble with the countdown timer. It seems to be not setting the time. I follow the instructions (below). However after setting the time, and confirming, the time I see is 0:00. No matter how many times I've tried, I still see 0:00. Is this some sort of glitch, or am I using it incorrectly. Many thanks.
