Someone who works in a different industry is credited with working on a film to which I contributed. How can I unlink her bio from the film IMDB information, and create a bio for myself/link it in the IMDB film info?
This may be a case where a project title is listed in the filmography of the wrong name page. As you've mentioned, there are two pages with the same name. I'm assuming that the difference between the name pages are the roman numerals to the right of the names.
For example,
Danielle Mackey (I) (The other person with the same name.)
Danielle Mackey (II) (The name page that identifies you.)
If this is the case, go to the title of the page that is misidentified and submit an update by changing the incorrect name from Mackey, Danielle (I) to Mackey, Danielle (II). You can also provide an explanation on why the data is being updated by clicking the check box to the left of the statement "provide an explanation to assist in processing this change" and post the URL of this discussion in the explanation section as proof.
Give at least 2-3 days for the submission to be updated on the IMDb servers.
I hope this helps. Please write back if you have any more questions.
