CM Locker prompting me to disable my default passcode?

[AC Question]

I've downloaded the CM Locker app three times or so now, and I've been having the same problem. Despite disabling the default system passcode after the initial prompt to do so, the lock screen still requires me to disable it again after restarting/turning on the phone. Is there any sort of fix to this? My phone is a Samsung Galaxy S4, running the 5.0.1 Android OS.
