When booking a session with some mentors, I'm seeing more than one option for the same time slot on the same day, which is quite confusing. In the screenshot attached, there are 3 different options labelled "17:00 - 17:30" for the same day. Does it make a difference which one I choose? What's the difference between them? Does this mean 3 people can book the same time slot? Or is it just one time slot that is mistakenly being displayed 3 times on the page?
