Scheduler in day mode, shows overlapping boxes, where the times do not overlap

Hi there, it seems that when the scheduler is given times that overlap on the 1/2 hour, it extends that box up until the next half hour mark. This causes the component to show appointments which "appear" to overlap, even though they do not.

Please see screen attached below

First appointment goes until 09:31, second appointment starts 09:32

However the component shows overlap (highlighted in red box), because the first appointment box has been extended up until the 10:00 half hour mark.

Is there anything that can be done about this, are there any settings which would allow for a more accurate representation of the timings?
