I am able to see all of my data currently, but I'm sure I'm one of the few lucky ones this time. I know that it's all related to the numerous issues that WU has been having with their servers over the past 6+ months. My best advice would be to give it some time to see if it shows up again.
You can always send WU support a message/email, but sadly I know they won't get back to you. But, it never hurts to try! Just know that it's nothing you're doing wrong, it's just yet another issue with WU.
Best of luck!
