There are two places in the site where addresses show up, and these two are unrelated.
1. When you enter an address for an individual card in your FTB, it will show up in the tree after publishing, under "contact info"
2. When you invite a member to your family site, a member profile is created for him, in addition to his individual profile in the tree. To view this profile and enter the relevant address, you have to go to the Site Members page.
I hope this distinction is now clear, let me know if you have additional questions.
