Cannot register for any cert exams

I must renew my expired MB-500 exam, but I'm outside the renewal window so I will have to take the exam again. If I navigate to the MS learn page here: https://learn.microsoft.com/en-us/credentials/certifications/d365-finance-and-operations-apps-developer-associate/?practice-assessment-type=certification about halfway down the page is a link to schedule the exam. The first time that I click that link it asks me to sign in, which I do, with this user. 

Then it brings me to my profile page, NOT to the exam registration page. I noticed that the fields with my name are blank but required. So I try to fill that in and save, but it doesnt save my name, it refreshes the page and my name is still blank. I can try this several times with several variations of the process and I can never get past this page. If I close the page, and start over while still signed in, go back to the MS learn page, click schedule exam, it takes me directly to my profile page and again,  the name is BLANK.

If I create a new account, I can access the schedule exam page. 

Its making me crazy PLEASE HELP!
