I have a contact not able to submit a ticket

I have one of my contacts signed up and he activate his account but when he login to the portal he was not able to find the submit button when he try to create new ticket and I noticed that his infoamtion are coming with null values.
Itried to delete it and I asked him to sign up again but we have the the same issue.
