when i open an app on my note 4, it will "click" to the first story

so when i open an app, i.e. facebook, the phone won't just open to my news feed - it will open up a recent post, as if i clicked on it. it starts out working normal, then if i re-open the app a half hour later, it does this clicking thing, then finally graduates to opening up on a post, but the back button doesn't take me to the news feed, it closes the app.
this was annoying enough on facebook, but today it started spreading to linkedin, which is annoying, because people can see when you click on their profile, and i am going to look like a complete stalker. i've tried the usual resets, this has been going on since i got the phone last year at launch, and i change out batteries daily.

any advice or settings i can change?
