About assignment of chapter 1

Can anyone please help me. I have completed 1st chapter and due date is till tomorrow. After completion i got the result like this(see picture). But again i am getting notification to complete my assignment, is there any other assignment left?

I’m using the Web interface (no mobile app), go to Overview

You should see if you have all the Graded Assignments green shields.
If you have them all, maybe it is taking into account Chapter 2 assignments?

Thankyou javier, i have all the assignments ticked with green color, it is also visible in the screenshot.
