Why does my Mortgage 1098 have the incorrect Outstanding Mortgage Principal?

Box 2 is NOT the current balance on the mortgage. Rather it’s the balance at the beginning of 2019. The definition of Box 2 is indicated on page 2 of the document.

Box 2. Shows the outstanding principal on the mortgage as of January 1, 2019. If the mortgage originated in 2019, shows the mortgage principal as of the date of origination. If the recipient/lender acquired the loan in 2019, shows the mortgage principal as of the date of acquisition
