Incorrect photo on actors page - have tried many times to change

https://www.imdb.com/name/nm1537809/?ref_=mv_close

On this page, the main image is a woman. She is not Christian Dunkley-Clark. 

I have reported the image, tried to edit it, all sorts of things, but it is still there.

There is another photo which IS the correct person, but it is the 2nd photo. Any help?
