If you go into app, you could check the list of who you follow and unfollow from there. Looks like you're on Android, so you can tap the 3 lines in the upper left corner, My Profile, Following, then if you see the names there for those people, you should be able to tap on “Following” next to that username and that will unfollow the person. Then it will remove them as a friend from your SparkPage.

I was cleaning up my friends list, and I was removing those who I had added, but not returned the gesture, and there are 3 names that are blacked out with no sparkpage, which I guess are phone app adds, but they do NOT appear in my friends list, so I cannot remove them via there either.
They just are listed in "People I have added but not added back"
Normally if a page goes offline they are still in your friends list and you can remove them from the list on your desktop version, but these 3 names don't appear in it.
Whats going on? These are the odd names in my list.

Edited to add : Oh and these 2 names are in my mutual list, but not appearing so I can be able to remove.
