Adding multiple instances of class series in scheduling

Hi guys, 

Im trying to set up a class series that is offered on different days/times. Ive dded in two different start date options - tues & sat (which appear correctly in the scheduling calendar in the back end) but when I embed the scheduling link on the web page, it doesnt show the calendar for the customer to select their preferred start date/day and when you go through the booking process its showing all dates for both tues and sat in the booking. Its showing two 'continue' buttons (possible bug with formatting?) but regardless of which continue button you press, all dates for both days are still showing (which means the customer cant select the day they want to do the class and their booking will show incorrect dates). Can anyone help. / provide insight for this?
