UE4 Marketplace account wont work

I am using the UE4 marketplace to sell some content I made that I think will be helpful to the community. When I made my account, It said to click a button to go to my account. It instead made me re-fill out the form I had just filled. I decided to hit the homepage button, and it said I hadn’t made an account. Then when I remade my account, it said the account was already made. I tried with completely different credentials and it still said it was made. What do I do?

it keeps saying Message: Seller Profile for is already created.
