xb7 xFi blocking access on profiles when a downtime schedule created, even though it shouldn't be

Today the wifi on my son's chromebook and PS4 and my daughter's TV stopped working unexpectedly. I checked and my work laptop, my phone, and other devices were fine.

As a troubleshooting step, I deleted the "bedtime" downtime profile (set to 11:30pm - 10am) and viola! My son's PS4 and chromebook were working again. But as soon as I created the downtime profile again, it paused his internet access.

The profile does NOT show paused and pausing/unpausing doesn't affect it.

This seems to be a bug in th xb7's downtime feature. Has anyone else seen this or know of a fix? It's really annoying to have to manually turn things on/off, especially if I'm already asleep!
