Problem with Fortune Chest – Granny Legend Review

Been really enjoying the game for the last couple months, other than the frequent ads. But recently have had problems with the higher end fortune chest. I save up gems to open them to upgrade high level characters but have had multiple times of receiving characters that should only be in the cheaper chest. Am I the only one with this issue? It is very frustrating to wait for that possible level up for my main character and get a lower level one!
