Quizzes using H5P Presentation

Hi team,

We're testing 2 h5p activities.

We couldn't work out why one course has little circles on the Tab buttons wherever they have developed a quiz(please check the screenshot). In the second course, developed the same way, the circles on the tabs are not visible.

I can't find any difference in activity settings, are you able to advise what could cause this?

Thanks

Sasha
