[Q] [Lollipop] Odd lockscreen behavior? topic

I recently flashed PA 5.0 on my LG G3 having previously used kitkat. One thing i'm noticing that's leaving a bad taste in my mouth is,
Why does the lockscreen go to the homescreen when I unlock the phone? It's supposed to show me the last app i had open, right?
At least that's what kitkat (and previous versions) did. Is this Google's change or Paranoid Android's change?
Or am I the only one with this issue?
