The dayparting drag&drop selection is currently encountering problems.
What may happen is that only the selection for the first day is saved, while the other days are left untouched.
What you can do now:
Always reopen the dayparting schedule to check the real saved values, you may need to manually add the section for the days/hours that haven't been saved properly.
What are we doing:
We have already started to work to fix this occurrence and we will send online a fix as soon as it's ready
If I'm able to display the correct selection, will it work?
Yes, the dayparting will work accordingly to the schedule selected
Are the checkboxs for the whole day/hour selection affected?
No, they are not: only the drag&drop selection has problems
