Some how your birthdate was entered incorrectly. I've reset it, and you should get a prompt to set your birthdate again. Keep in mind you must be at least 13 years old to use the hub and any community features.
As for the projects saying you're not the owner. It seems like they just need to be synched up again, @RobinsonX can you have him send the projects to you so you can fix them?
Edit:
I just looked at your account and see you have two accounts. Are you sure you're logged into the correct account that created the project?
If you create a project on one account, then log out and log into another, that new account won't have ownership of that project to submit it to the hub.
