Appointments Starting at Set Times

Howdy,

Not sure how to set available appointments at set times.

Service provider has these appointment openings:
Wed 10:00-11, 11:10-12:10, 12:20-1:20
Friday :1:30-2:30, 2:40-3:40, 4:50-5:50,
Saturday : 10:00-11:00, 11:10-12:10, Break til 1, 1:00-2:00, 2:10-3:10, 3:20-4:20 clinic

I have tried padding but that didn't work for anything beyond the first two appointment openings.

I've turned on service access if you need to login and look at the settings.

Cheers,
Casper
