CFAI R31 EOC #6 (Two-bond Hedge) V4 p189 all, its, particular, percentage, something

I’m having trouble getting the same values as the CFAI solution. In particular, when they calculate the percentage of price changes for the 2 year and the 10 year notes, they get values that don’t match mine.
Price of 2-year bond = 106.650
Price for increase in yield = 106.122
Price for decrease in yield = 107.300
So to calculate the price change I did:
(106.122 - 106.650)/106.650 = -0.495%
They say its -0.528%
Also, all of my other percentages are off. Am I missing something here?
I also can’t get the values they use in their example in the text.

106.122-106.65 = -.528

Yeah, it can get tricky with the wording.
