In the category called "Address" you will find either a number of address fields, a button called "More info" and a button called "Add new address type" or a button called "More info" and a button called "Add new address type "(see images below).
Note that if a building does not have an address linked to it, the button called "More info" will be inactive. In other words, if a building does not have an address linked to it, you will not be able to use the button called "More info".
Using the category called address you can:
link addresses to the building you are working with
view how many addresses are linked to the building you are working with
remove addresses from the building you are working with.
