Credit doesn't show up

Hello. I'm the director of a short movie called "Tragedy". https://www.imdb.com/title/tt37876733/ And I can't seem to add the main actor - Radoslav I. Todorov - https://www.imdb.com/name/nm9904580/ I submitted his name way back when I submitted the title, but it still doesn't show up. I guess it's a glitch or something. He is the main actor and his order is "1". Thank you.
