Hello @Veena
Thanks for posting this in the Canvas Community.
I apologize that you are having trouble with your home page. I'm not sure if you are asking as an instructor or student. Feel free to clarify!
Without being able to look into your specific example, I can't say 100% what is causing this to happen. You might need to contact canvas support to have them take a look at the configuration of the course and module Requirements/Prerequisites setup within it. If your course is using module Requirements or Prerequisites and the home page is not listed as one of the items you have to complete for the module, it won't not show as being a required completed item.
HERE is a guide on setting up Module Requirements.

Hopefully this helps a bit!
