Farm Club Mystery Companion Rewards

Hi! I’m at level 1611 in Farm Hero’s Saga. I’ve just recently completed all of the companions in the game. But there is 3 of the rewards that still have question marks by them. So I can’t achieve the rewards. I’m wondering how can I fix this? Also I had all my inbox erased somehow. Which I had a lot of lives given to me and requests from others. I’m wondering how that happened as well. One minute they were there and the next they were gone. Thank you!
