Hi Rosie!
That toggle will actually allow them to select sessions that are taking place at the same time.
I see you managing this one of two ways - you could put all of the sessions into a session group, which will make it so that the attendee can only select one. Or you can set up an Advanced Rule and set a limit of only one session selection.
Hope that helps!
