Unfortunately, our Update System does not handle additions well when names include numbers or lower caps.
I would encourage you to go to this page: http://www.imdb.com/helpdesk/data_ver... and fill in the form with all the credit information. You will also need to include a URL pointing to the verification that you are credited under that name (such as a screen-shot of your on-screen credit) at least one link is mandatory. If you have more than three, use the 'comment' field to add them.
Enter any additional information, comment or feedback in the 'comment' field. The more data/evidence you supply, the better, and submit the form.
