Login Question: Terms & Conditions

Hi Guys - quick question.

My app login requires to agree to terms and conditions (need to check a check box).
What does it mean when I see in the login sheet instances when the “agreed” check box isn’t check? Does it mean that the user managed to login without checking the box somehow?

(The 2 lines shown here are from the same user.)
