[SOLVED] Check icon from Review layer on graded questions stopped showing

Hello everyone,

I converted an existant Storyline 2 project to Storyline 3 project. That worked almost great. 

When I do the quiz and review it from the result slide, the graded questions with multiple choice and multiple response questions type don't show the check icon in the review slides.

But when I create a new quiz in Storyline 3 with some multiple choice and multiple reponses, the check icon is present.

And if I copy the converted slides to a new Storyline 3 project, the check icon show again in the review slide.

Is there a bug with the SL2 to SL3 conversion? Or it's a setting that I missed?

Some examples in attachment

Thank you for your help!
