Critical bug

Hi ! This app is great but there is a bug that can be very critical for users. When you define a 6 time per day schedule, the application will only notify 4 times: expected: 1h, 5h, 9h, 13h, 17h, 21h; observed: 9h, 13h, 17, 21h.
Reminder at 1 AM and 5 AM are not set. Could be deadly depending of the medicine. Do you plan a quick fix for that?
