Finance Lease - beginning of year payments/interest calculat beginning, interest, liability

MonkeyBusiness

I’m confused on Schweser vs. CFAI calcuations for interest pamyments for beginning of year payments on finance leases.
If you open the Schwesr Notes, vol. 2, p.65/66, the solution for problem 7 says that for Year 1, the interest payment is 2734.  This makes sense I suppose, since your lease liability is reduced right away as you pay on Jan. 1., then get charged interest on that balance. However, if you now open the CFAI books, vol. 2, to page 81, they also list a table for a finance lease payment schedule, also strucured as beginning of year payments.
Where I’m confused it that the CFAI has ZERO for Year 1 interest, while Schweser has an interest payment for Year 1. What am I missing here as to why these seemingly two identically structured lease payments have different interest methods for Year 1?
