Default [Q] Losing root on SkyNote 4.3

Hey guys, I have been losing root each time I reboot on SkyNote. I saw the problem popped up on dev thread but couldn't find an answer. I have noticed it happens more often after Xposed Modules installed. Still happens without Xposed installed, just takes a few reboots. Only way to keep root is to install rom again through CWM. Any way to fix or an easier way to root a 4.3? Thanks guys.
