Writer attribute amendment

Hi staff I have added my name to a podcast episode where my story has been broadcast. I included the name of the story in the "attribute" field because there's another story by a different writer in the same episode. However, this attribute appears on my main page and I wanted to delete the story name and just have "writer" in case I am involved in another future episode. Does anyone know how I can do this? Hope I've explained that well enough.
