Page display not correct

Hello,

Can you help me with make pages generated from a plugin call Sensei display correctly on your theme? I like accesspress lite because of the elegance and simplest and really want to use it with Sensei. The course and lessons pages take up the full width of the page. Because these lessons are private I can’t publicly give you link to the course page. I created a dummy page so you can see what I am talking about.

Thanks.
