I have noticed the same thing in my Fight Camp. I looked at my camp's Earnings Leaders page, and while the figures displayed there are correct, if I click on "VIEW" to see another member's financial history this season, I get my wager history even though it's actually someone else's. I'll get a couple of screenshots so you can see what I'm talking about.
Edit: Links to screenshots...
Screenshot 1 Screenshot 2 Screenshot 3 The first shot is of another member of my camp's wager history this season, which matches mine as you will see in screenshot 2, so screenshot 1 is incorrect. The 3rd screenshot is my camp's Earnings Leaders page, which displays the correct bankroll totals.
I've sent a report along to admin & the programmer.
