Why will my SG4 ONLY lock with the swipe screen lock?

[AC Question]

I've tried everything, I even rebooted my phone to factory settings... TWICE! Nothing seems to work. I've tried to set up passwords, even trying every option. Whenever I put my phone in sleep mode (when I press the power button) and turn it back on, the swipe screen lock is there again. The only time the password that I entered is there is when I restart the phone, but then when I shut it off again, the screen swipe is back. If I leave it alone for five or so minutes, the regular password is back, but then it goes back to the screen swipe again. Please help me fix this issue, I don't want someone getting into my phone.
