That the icons are not in the box, it is a display issue.

That is done on purpose. Look at the icons. The ones in the box are for gamertags/gamer IDs such as Xbox Live or Steam. The ones below the box are communication user names for programs such as Skype.
If it's not out of place it looks fugle. Be nice if it was just all together.
And voila.
On my profile where it displays my Gamertag and my Steam ID, it shows them as unavailable or does not exist
I retyped it and stuff, but it won't display them for some reason
For me, the Gamertag and Skype work fine, but the Steam ID it says doesn't exist. If you typed it in correctly, it might be that Steam changed their API or something and the module is outdated, or it might take awhile to update after you recently changed it, not sure.
