If you have the mission pass ticket in your inventory, place it into storage. As long as you have the ticket in inventory you won't be able to get the rewards. Once you remove and placed the ticket in storage, go back, and claim your rewards.
There was a bug with the mission pass ticket. So they disable the use of it. And must not be in your inventory when trying to claim your rewards. You can go to Swap Shop 2 and exchange the mission pass ticket for 200 SG since the ticket is useless and bugged for the time being. And for now, we need to go through the mission pass itself to unlock it.
