I just lost all of my special level for all of my …….

Please help I just lost of my special signature level ups all on my classic Iron Fist. I went use just one to level him up and then I was going to do others. it never. asked for any confiramtion it just took all off them without any confirmation. It took both of the ones for the general or basic level ups and it took all of my ones for my mystics. My Iron Fist is a three star that it happened to. He went from like a level 40 to level 99, which I did not want to have happen. This took. my stone that was 99 It took about 30 or 40 basic stones. It took about 20 or 30 mystic stones. What can I do to recover all of these and put my Iron Fist back to where he was? I think may have a bug.
