Why can't i disable the slide to unlock pattern code on my Samsung galaxy tab A

[Android Central Question]

I disabled the lock screen but now after im on my tablet for45 seconds or less it goes to a lock screen that says slide to unlock. I do not know the pattern

Is this a pattern that you once created?

Slide to unlock means run your finger across the screen - try one lower corner to the opposite upper corner.

Then go back to Settings and set it to None.
