I've just released a tiny update to Time Out, to fix a couple of issues.
Version 2.2.1 includes a fix for scheduling issue, where it was incorrectly adding the sleep duration to the due time after waking from sleep. It also includes a fix for breaks set to a frequency of daily (or longer) and with an Available time range set, where it was pushing the due time out by a day.
If you are using the Mac App Store edition, you can update via the App Store app once it has been approved (maybe later today or tomorrow).
If you are using the direct edition, you can use the Check for Updates feature in the app to update.
Otherwise, download Time Out 2.2.1 now.
