Problems with the edit interface.

Hello, I am Javi, the creator of the web series "La historia de Huesitos": https://www.imdb.com/es-es/title/tt38356576/?ref_=fn_all_ttl_1 Some credits on the title page are showing duplicates without their last names and the wrong people (IMDb merged my new actors with existing people with the same name). The problem is that these credits appear publicly on the title page, but they do not show up in the “Edit page” interface, and nobody of the art the art departament appear in the edit interface too, so I cannot correct or delete them myself. Could you please split these credits from the existing names and allow me to create new name entries for the correct people? Thank you very much for your help.
