Trouble getting time blocks to display correctly

I'm trying to configure Appointments+ time blocks but I'm not having much luck.

The appointment blocks I need are as follows:

12.45pm - 2.45pm
3.15pm - 5.15pm
5.45pm - 7.45pm

9.45am - 11.45am
12.30pm - 2.30pm
3.00pm - 5.00pm
5.30pm - 7.30pm

Ideally if I can get the time blocks displaying exactly like that (with start and end time) then that would be excellent.

But first I'm unable to get the time slots working as desired. I've attempted to use breaks to control when the times are shown however this seems to make little difference. The blocks still display sequentially.

eg: 12.45pm | 2.45pm | 4.45pm

Any help here would be greatly appreciated.
