Not all bookings with consecutive timeslots are displayed in full

[x]: This is a bug and not a question.

[x]: I understand that the best way to resolve this issue is to solve it and propose a Pull Request.

Describe the bug**

If a booking has been entered that occupies several consecutive time slots, it will not be displayed in full during the afternoon hours.

To Reproduce**

Steps to reproduce the behavior:

1. Enter a booking that occupies multiple consecutive time slots. For example, lessons 4.-5.

Expected behavior**

All calendar views should display all bookings on the page /Web/schedule.php

Screenshots**

First calendar view, everything is correct:

Second calendar view, one timeslot is empty. Although it should display a reservation there.

Additional context**

Maybe there's a problem with the naming of time slots, since the problem only occurs with afternoon times?
My time slots are as follows:

08:00 - 08:30 8.00-8.30
08:30 - 09:40 1. tund (8.30-9.40)
09:50 - 11:00 2. tund (9.50-11.00)
11:00 - 11:30 Vahetund (11.00-11.30)
11:30 - 12:40 3. tund (11.30-12.40)
12:40 - 13:30 Kasulik aeg (12.40-13.30)
13:30 - 14:40 4. tund (13.30-14.40)
14:50 - 16:00 5. tund (14.50-16.00)
16:00 - 17:00 16.00-17.00
17:00 - 18:00 17.00-18.00
