@Najee12,
There are two parts of the Property and rooms section which can be edited. Your image is showing the first one, Property type. You need to save any changes that you've made in there, and then click the second edit link, which is for Rooms and spaces.
After you click the edit button, you will see a list of all the rooms that are available to guests. To make edits, click the of each room label to expand it and display options. The below image shows a list of rooms with each category collapsed (the down pointing arrows to the right indicate that the row can be dropped down for more details).
I clicked the Bedroom row to expand the category and see what options are available (the arrow is pointing up to indicate that the category can be collapsed). In my prior image of this category I didn't select Shared with others and the button remained on the left and gray, but did select in the below image, and the button is slid to the right, has a check mark, and is black.
If Shared with others in selected under the Full bathroom category (see below), uncheck it to remove that description.
