Cast correct declined on The Good Liar

There are 10 credits listed on The Good Liar's page which do not have credit order and I verified that they are not listed in the end credits. I tried to add the attribute (uncredited) to them (and in some cases fix the character description to meet IMDb guidelines) but all were denied. I'm not sure what proof I could provide except the entire cast list that you could then see that they aren't listed. That would be a pain because it's a BluRay and I can't screencap from it. Can we get these fixed without screencaps?
