Under very specific circumstances, with slots for multiple teachers, the UI displays the wrong name for a slot when pagination causes the time slot to be split over 2 pages. For example, the slot at 1:00-1:20 will show as Teacher A on both pages 1 and 2.

Here are some specific values that should exhibit the problem:

1. Enrol 2 or more teachers on a course
2. Create a new scheduler with default values
3. Create multiple slots for 2 teachers with the following values: 15-16th June 2020, 10:00-17:00, 20 mins per slot (or 15 + 5 break)
4. The last slot on page 1 will be the same as the first slot on page 2 and you will be unable to see the same time slot for the other teacher, making it impossible to book

I've been through many other combinations, most of which work fine - 9-5 works fine, 15 minute slots works fine, only having one day seems to work fine too. It's very confusing!
