Assements tab is not working

Hi,

After the latest update the assessment tab of coursepress is not working properly. After selecting a course it shows no students assessments. In my screenshot, you can see there are 2 assessments units. The problem is those assessment elements are not showing up in assessment tab thus there's no way to grade file uploads and answer field answers. It also says there are 0 students in the class but actually there are 4.

2. also after the latest update the menu items sometimes looks like the screenshot.

How to resolve these?
