storyline 360 Review Quiz displays incorrect on correct answers

I'm having the same issue. It's extremely annoying as it does not appear to follow a pattern. Although some questions seem to run into it more frequently than others, there are times when all are correctly classified during review. 

Scenario: I have a set of questions, picked randomly from a question bank. Mostly multiple choice, with a few select all that apply. Most, but not all questions, have the answer shuffle feature enabled. Upon completing the questions, before submitting, the user can go back and review their answers. When they're happy with what they entered they can submit the answers. The results slide allows them to go back and see which questions they got wrong and which they got right.

Issue: This is where the problem surfaces, following no evident pattern. Sometimes a correct answer (in a selected state), with a green checkmark next to it is accompanied by a red "Incorrect" banner. No matter what my settings are this should NEVER HAPPEN. The green checkmark and the banner are out of sync with each other. Checkmark is correct, banner, and the corresponding sore are wrong.

More about config; All the slides in the bank are set to "resume saved state". Additionally, the Results slide also includes a button that will Reset the results and allow users to re-do the quiz. There are no restrictions on the number of times that a user can do any of these (review before submitting, review after submitting, re-try).  

Edit: I just tried using "decide automatically" and it's still hit and miss.
