Bug in schedule helper?

I have an existing schedule helper that was set up in 2022.10.x and I’ve upgraded to 2022.11.x. Not sure if the version change has done anything but I can’t seem to set any periods on Sunday during a time that was previous scheduled in this schedule. It goes blank and sends this message, even after saving a blank schedule for Sunday, then going back and trying to set up a new schedule for Sunday again.

Update: This is even happening on a new schedule and it appears to be a GUI issue as the .storage/schedule file has the correct data.

Same here. Schedule helper UI is not showing periods correctly - only for first day.

Home Assistant 2022.11.1
Supervisor 2022.10.2
Operating System 9.3
Frontend 20221102.1 - latest

Seeing the same thing with 2022.11 as well.

Looks like there are several issues open regarding bugs in the Schedule helper including this one that seems to be the most related but aren’t getting any love even though they are getting to be a few months old.

Will be curious to see if the schedules re-appear tomorrow (Monday)

Still sam with my settings:
Home Assistant 2022.11.4
Supervisor 2022.11.2
Operating System 9.3
Frontend 20221108.0 - latest

Is there a way to find the actual stored setting somewhere?
