That's strange I had a look & can confirm that app reports them as sleeping but other apps I have tried don't say they're offline unless I shut them off manually, so I wouldn't worry about it.
Try setting the battery profile back to balanced as that use's the interactive governor, as I found with antutu benchmarking app I scored better with the interactive governor than I did with the performance governor.
