Appointments - break not showing in schedule

hi folks,

we have hour appointments, with a 30 minute break between on appts+.
we've set it up on the back-end (click the plus, put in the break time, click the plus...)

But on the front end of the site, it doesn't really care about our breaks.

it just fits in the one hour meeting after the next... endlessly.

rather disconcerting if you have to go to the loo and such.

can you please have a lookie see what we're doing wrong? or why it's not playing ball?

thanks

i've extended back-end support access.

tx.
