Differing Extranet options

I was wondering if anyone could help. I have two apartments on Booking.com that when accessed via the Extranet have a Rates and Availabilty Tab, which I use for setting the rates and occupency etc. I have just added a third property to booking.com but the extranet interface is different, it now has the option of Calendar and Pricing instead of Rates and Avaolability, which is format I would like. Can anyone help? As far as I can see I've set all properties up the same but think i must have a setting slightly different. Thanks in advance.
