Credits merged with another person

Hello, my stage name is Rancho, but there is another person who also has this name and our credits are mixed up and when I want to enter new credits it doesn't give me the option to be another person "Rancho (I)" is there a way to correct this? This is the page https://www.imdb.com/name/nm11020460/?ref_=fn_all_nme_1 all of the acting credits are not mine and the bio is also not mine
