Bugs in content types

Hi , I have some problems with the quiz.

1. There are 8 questions randomly choosen from a set of 13 questions and I allow repetition in case of the person does not reach the required 80%. As the questions are various type (drag und drop, multiple choice, single choice) in each round a different total of points can be reached.

One person failed in round one with 19 out of 28 points; Second round 14 point are possible she reached 14. At the end of round 2 the result shows 14 / 15. The number of possible points in round two is wrong. See attached files.

Hi - On a Mac laptop pro in the latest version of Mojave I have created a drag n drop exercise and created correct coordinated drop zones and labels for the drop zones. I have specified that each text label will have one drop zone. However, when I play the activity in Moodle, when I answer correctly and place the labels where they belong, the results show of all of my answers are incorrect with red text and a -1x. Is this a bug or have I possibly missed a setting in one of the set up menus?

Thanks -
