I'm using Moodle 2.6 and this is our problem. There is a test consisting of a reading. When a student mark it as completed, they earn a badge. It has worked OK for all, but there are two "false" winners of this badge. They have not marked the activity as completed (s. picture 1), but they have earned the badge (s. picture 2). They are Anja and Ivo.
Can someone tell me why is this so?
