3 issues with appointment+: Price issues: I have added

3 issues with appointment+:

Price issues:
I have added a price for my services and chosen AUD as the currency. When I test on live site, the price almost doubles, see link... http://burnfatbuildmuscle.com.au/make-an-appointment/?app_service_id=1
The service list price on the back end $20 not 27, have been through all set up options in appointment+, market press and, membership cannot find anything.

Calendar does not refresh when a change of service is chosen:
The page does not refresh when a different service is selected, hence clients will still see the calendar for the previous service.
- Can the "show available times" BUTTON be larger are customised?

Change the options seen in appointments"Please check the appointment details below and confirm:":
Can i remove service provider?

Thank you in advance
