cm file manager

I cant access files via CM-File Manger which require root access. I am using supersu and set following options:

enabled root access for the file manager via superSU

set access-mode inside filemanager to "root access mode"

enabled root access to "Apps and ADB" inside CM Developer options

SuperSU version: v2.79

CM nightly version: cm-14.1-20161222-NIGHTLY-bullhead

Can someone confirm this? Or does it work without superSU?

Edit: Removing SuperSU and using Privacy Guard instead didnt solve the problem
