Formating problem on the course shelve

It seems that there is a formating problem on the course shelve.

On one computer there are
2 lessons
2 lessons
1 lessons
in a row. Than it starts again.

On another computer are
3 lessons,
2 lessons
in a row before it starts again.

I hope you can get what I mean.

Hi Vera,

We are aware of this issue and will hopefully have it fixed soon.
