Android 6.0.1 - Galaxy S5: Bubbles Lock Screen

[AC Question]

Seems that most of the solutions for my problem relate to the S4 Note. For my lock screen, instead of the swipe pattern screen, it displays exploding bubbles which just require a swipe to return to the screen I was at leaving me vulnerable for someone to do what every they want if they pickup my phone. I went to a Sprint Store and she thought it was resolved but I left the store and it came right back. I'd like to save having to backup and restore my phone. It has been going on for some time and I would sure appreciate some help. THANKS!!
