I have "tried" to setup a booking feature for booking

Hi,

I have "tried" to setup a booking feature for booking a meeting room.
I have one service provider (the room) and 4 services, for duration (30min, 60min, 2hrs, 4hrs)

2 major issues;
1) When selecting 60min service, followed by date and desiered time, the confirmation sections displays a different service in the info and the booking itselves can be other duration.. in worst case: selected 30 min meeting, Got reciept for 60 min and boolking (my bookings) indicates 2hrs.

2) When selecing on a day with no bookings the 2hrs service, every second hour dissapears for the time schedule.....

Here are my codes that I use:
[app_my_appointments ... allow_cancel="1"]
[app_services ... worker="4"]
[app_monthly_schedule]
[app_pagination month="1"]
[app_confirmation]
