Am I missing something.

On 2020 Pro Series, I entered a bona fide residence start date of prior to 2020 and an end date of 12/16/20. That is 341 days of 366 that client lived overseas in 2020, or 93.2%.  .932 appears on line 39.  Pro Series then automatically multiples line 37 (max exclusion) of $107,600 by line 39 (.932) and yields a result on line 40 of $98,699.  When I manually multiply $107,600 by .932 I get $100,283.  IS THERE AN ERROR IN THE BASE OF SOFTWARE OR AM I MISSING SOMETHING.  (NOTE:  I have housing allowance entries in Part VI)  Thank you
