I can't change the price and allotment of the room. My extranet looks different than before. Please help

There are already several bookings from booking.com. I can't see the details of the booking code. 
When I entered the extranet I was directed to enter to fill in the data from the beginning. We can't refuse guests. There is also no notification from Booking.com via email and there is no type of payment either. Please inform as soon as possible. This is very urgent for us
