Really simple economic math bug

Hey Stardock - I did do a quick search first before posting - hard to believe nobody else has mentioned this simple math bug in the Economy screen.

In my screenshot you can see:

GDP = 4,352.68
Trade route income = 488.99
Taxes are set at 25% (assuming this is a 25% income multiplier?)

So my total income should be 4,352.68 + 488.99 * 1.25 = 6,052.08

BUT - the 25% rate is being applied as reducing factor:

4,352.68 + 488.99 * 0.25% = 1,210.42

So I'm losing nearly 5000 credits per turn!
