After passing a lesson I am still shown the same lesson

Even after passing a lesson, when I log in another time, I am being directed to the same lesson and my progress is all lost and I have to redo so many times yet I am brought to the same lesson. Please help me asap as I cannot proceed forward due to this issue. Thanks
