I googled how to edit the contributing artists and there were plenty of results. I followed the instructions and selected all the files, right clicked and went into properties and then details. Once I clicked details though, there wasn't option or anything to edit contributing artist. I tried double clicking and right clicking but nothing happened. I feel stupid because I bet the solution to this will be really simple, but I can't figure it out and I would really like to edit it. Hopefully someone could please resolve this issue for me. Thanks.
