My profile doesn't display

Please, what’s wrong with my FCC account? I have set up my profile to be public but your platform does not take this into account and does not display my profile. I have completed the Javascript Algorithms And Data Structures courses but my certificate is not displayed. Worse still, when I connect with another browser, your platform displays my profile well but with only half of the challenges met. As a result, I am forced to use the same computer and browser for fear of losing tracks of all the challenges already met. What can I do about it?
Here is the url link of my account:
Finally, thank you for this great online programming learning platform!
