You use to be able to keep changing the reward and now once you go past one you can’t go back. I think you need to change it back. Also if you use gold bars for extra moves and you don’t use them all you should be able to keep the unused for the next level.

Being able to carry forward any unused extra moves that have been purchased is a very popular suggestion. As such your idea has been suggested many times previously. This makes your idea a duplicate and I am sorry to say duplicate ideas aren't allowed.

Please consider adding your vote to an existing idea.
