Hi There

i have following problem: on the dentsist site you can book either dental care or Normal check up, there are 2 service providers:
Service Provider1: ONLY Dental Care
Serviceprovider2: Dental Care and Normal Checkup
now if i log to the homepage and book the normal check up with the serviceprovider2, the calender shows the right free slots however if i choose dental care with with the same service provider (2) the calendar shows all free slots, though they are not free. since the service provider can only service one customer at the time... this has only occured after the last update... PLEASE HELP!!!!!!

the service provider1 works perfectly as this one offers only one service

THANK YOU !!!
