If you want to delete a property, you can do so from the control panel. Go to Properties/My Properties in the main menu.
Once inside your list of properties, you’ll see an orange Edit button in the right-hand column of each property.
"By clicking on it, all available options for editing that property will open."
To delete the specific property, go to the Options tab — the last one — and click the Delete this property button located in the lower right corner.
A confirmation window will appear. Remember that once the property is deleted, it cannot be recovered.
