I set up working hours: every day 10am-9pm, sunday 11am-6pm

Hi
I set up working hours: every day 10am-9pm, sunday 11am-6pm , duration 90min (with custom code inserted in functions.php to stretch it to 120 min so we can have a break time after eacj session) Available capacity:3 , set starting date to Oct 1 as this is when we open.
I added the shortcodes:
[app_services ... select="Available service:"]
[app_pagination ... month="1"]
[app_monthly_schedule ... date="2013-10-01"]
[app_confirmation]
[app_paypal ... item_name="Payment for SERVICE"]

The calendar works BUT there are rows of weekdays blocked out... AND clicking on pagination "next month" goes to August instead which should not be visible.
(I don't want to publish my site due to spam) I can email you the URL if you want.
