2 new bugs (statistics and classement)

Hello,

sorry but we have 2 new bugs with Quiz Maker.

1// in the statistics, the month showed are not the actually month. Very strange. We actually see the July 06 to August 31. We are the 25 of June.

2// in the “classement” (in french) we have a error.
Notice: Trying to get property ‘data’ of non-object in /public_html/wp-content/plugins/quiz-maker/admin/partials/results/quiz-maker-results-display.php on line 81

So what can we do to fix this 2 bugs ?

Thank you.

Regard.
