BMW 340i deal, dealer lease calculations are off?

Hi, I am getting a slightly lower monthly payment, not sure why the leasehckr calculator numbers are not lining up with the dealer, any ideas?

It’s supposed to be a $0 drive off with $4500 incentive (loyalty + lease) applied to sale price of $50,800. Tax is @ 7.25

Only $2071 of the $4500 rebate is applied as a CCR. The rest is used to pay the drive-offs.

Thanks for your insight. Would you recommend structuring it this way? The dealer is committed to the stated MF and selling price, shouldn’t make a difference to them if I move stuff around. The intent was that 0 drive off results in the least risk and avoid paying taxes on the CCR.
