Quirk with Schedule daily events

I came across an oddity when playing with scheduling events. I’m using the Once a Day Smartapp to control an outlet in my house. The outlet has my power cord adapter in it for my phone. I want it to turn on at 10:30 at night, and then off at 6:00 in the morning.

The six in the morning off command works fine, but the 10:30 at night doesn’t trigger. So I played around with times. If I set it to 10:30pm on, and then 11:59pm off, and then 12:01am on, and 6:00am off, then things seems to work okay.

So it seems that once the off command happens, the cloud doesn’t process and more commands for that program. Anyone else experience anything like this?

@chrisb I’ve been using Once a Day to control several outside lights on my house. I started with Sunset/Sunrise but it wasn’t reliable. But The Once a Day seems reliable. I’m using On at 2130 and Off at 0600.
