Buffer time shifts start time off of top/bottom of hour

It is customary in business to have meetings start at the :00 (top) or :30 (bottom) of the hour. I am using a 30 minute meeting in bookings.

However, if I include a buffer time, (5 minutes for example), then all the suggested meeting times shift to :05 and :35. This is very odd to present to clients, and essentially makes the buffer feature unusable.

Is there a way to force meetings to the :00 and :30 with a buffer time? Here are some images that illustrate the issue. Image 4 shows the "glitch".
