How to reverse calculate MF from Dealer sheet–something looks off here on this BMW

Does anyone know how to determine MF from a dealer sheet? Long story short, I have a pending deal that was great, but my wife wants us to trade our car in on it. Our car has 10k neg egg (I know it’s not the best financial decision, so please spare the “just write a check for the 10k” opinions😅)

The price went up $373/m with the 10k negg egg which looks off giving the buy rate MF (which I got at first) is .00115. It looks like they marked it up on the trade, but I need to verify before I go back and correct it.

Any help is appreciated!

Lease Cal is showing $298 increase with the trade-in vs. the dealer showing $373

Would need to see the dealer sheet with what information is on it to be able to tell you if/how to use the information on it
