Need help creating a new name. System error.

I’m trying to create a new name page to add to this documentary https://www.imdb.com/title/tt2205591/ However no matter what I do it won’t let me create a new ‘Kevin Smith’. I click on Result not shown, and the drop down menu disappears but nothing happens. Kevin Smith with no roman numeral and it all repeats itself. I seem to remember this happen with this exact name once before. Can someone see if this happens to them as well? If you can get a new Kevin Smith created can you either send me the the name with the roman numeral or go to the documentary and add it for me? Thanks.
