Recurring Completion Issue

Guys this seems to be a recurring problem, i complete challenges and they do not seem to register. I do not have duplicate accounts and i sign in at every session yet this continues. Can anyone tell me why or help figure this out once and for all.

Can you explain what you mean when you say that they “do not seem to register”?

What i mean is that everything that i have done from the beginning starting from HTML up to date is not checked off in the curriculum.

Does it show up on your profile timeline?
