Problems with apartments managment

Hi I have house with 3 apartments. I registered them and try to add to booking.com but it seems that I made some mistake. These are my apartments which i added to booking https://prnt.sc/op6wwh, but I can't manage them. When I go to property layout, I only can see this post: https://prnt.sc/op6y6d But I don't want this, I want to manage my Apartments names " Apartman A1, Apartman A2 and Apartman A3". How can I do that?
