Can't change the available calendar

I have 2 properties. The first I can select the availability calendar and easily choose the dates I want to block off, then select promotions I want to apply to certain dates etc.

The second property I accidently selected that there were 2 properties instead of 1. When I try to manage that location the calendar interface is totally different and there isn't an option for promotions etc. It seems to be in a hotel format which is not what I want. How can I modify this so both properties have similar calendars etc?

I emailed booking.com several days ago but no one has replied to my message.
