Looking at my online statements I find different balances on different pages of .bomb:

1) RDM balance:

"My Account" page: 188180 miles

"Ending balance": 204067 miles
appears on the page, when I click "View activity since last statement".

So I am wondering, where does the difference of 15113 miles come from?
What is the actual, usable mileage balance?

2) RPU:

"My Account" page: 12 RPUs
6 RPUs xp 1/31/2016
6 RPUs xp 1/31/2017

Now I pull up a reservation and want to apply an RPU. The window "How would you like to upgrade" appears with the option to redeem a RPU. But, here it shows 14 RPUs available - 8 xp 1/31/2016, 6 xp 1/31/2017?

Just not sure, how the "My Account" page misses two RPUs?

Anybody else looking at similar balance scenarios?
