Default screen timeout issue

i just got my note3 the other day. i changed the screen timeout from the default 30 seconds to 5 minutes. then whenever i power off and on the phone, the screen timeout is back to default 30 seconds.

i am running stock android 4.3 and model N9005.

anyone has the same issue?

** updates
i was searching this issue online when someone mentioned the 'profile scheduler' app has the screen timeout setting for 30 seconds. that seems to be the issue for me.
