If it helps, since I just uploaded a profile picture... I had the same problem what I did was you can notice that you can crop the picture there is an arrow button or something similar, you can move that inwards and make it so the picture only focuses your face... Basically a circle around your face... I think their system detects objects in the background so try to focus on the face only.
