Sleep songs error

I love this app and use it to fall asleep every night. It worked perfectly until the last update. Now although I set it to play for 1hour which it did in the past, now it resets itself to play for only 10 minutes at a time. Very frustrated. Please fix this problem as it spoils it for me. I can no longer use it to sleep as 10 minutes is not long enough
