[BUG] Latest release 2.16.0 - no graph

[lazzio7]

Describe the bug

I am wondering, if you are facing same issue.

After Friday’s update to version 2.16.0, graphs which showed alerts/findings are not present any more, also within overview page Pie chart is missing too. Just empty for all.

Thank You
