Why are two directors listed? 2 Tony Santiago? IMDB Error?

The promotional video box as well as the picture only list Jorge Ameer as the director. Why is there another person listed as additional director? I believe this must be an error considering this picture was made by Jorge Ameers film company Hollywood Independents. Also, there are two Tony Sagos-Santiagos (these are four different people when it should be only two) I shall submit this for correction.
