Missing checkboxes

First of all: Thank you!!! Thank you for creating a simple room booking plugin that does what I need it to and not a billion useless things and then doesn’t actually work at the end of the day! I spent so long looking for something like this. Thank you!

Anyway: Issue, though. I’ve set my opening hours to be from 8AM to 10PM, and all the time slots do show up in the booking process. BUT there are only checkboxes up to 2:30PM. So every time slot from 8AM to 2:30PM has a checkbox, and after that it’s just blank. It also doesn’t say “OPEN” after 2:30. Did I miss a setting somewhere?
