Quiz review and result slide diplays incorrect feedback
The following problem is reported by some of our users.
Users answer 26 MPC questions in a quiz randomly taken from a set of question banks. They have to answer at least 24 questions correctly. However, when they give 24 or more correct answers the result screen gives a lower number of correct answers (see first screenshot; unfortuanletly in Dutch but but is shows that user has 22 answers correct while it must be 24). When they review their given answers they see answers marked as incorrect which are in fact correct (see secoond screenshot; it shows that the given answer is correct (green box) while the message says 'incorrect'). The score is calculated correctly, and also the result screen displayes the result correctly (see first screenshot; result is 'passed').
The problem only seems to occur for some users, others have no problems and so far we where not able to reproduce the problem. Hope you can help!
