I just got a couple of emails about this. It looks like the numbers are all correct on my admin side and in the database. The problem is just on the display on your end. The difference should be exactly the amount that you have earned in referrals so far. So we just need to have it add your referrals back into the display.
IT (DH!) is working on it. He may have been tinkering with something in the display and didn't realize that he changed that part of it. But since I can see the right account balances on my end, I'm confident it can be fixed really quickly.
