DAT01 Baseline Financial Forecast and DAT02 PY Revenue to CY

Hi does anybody know why the grand-totals for both (see attached screenshots) are not the same?

The DAT02 screenshot is from Lesson 15 - 4.7 Check Your Build in the L2MB Sprint 1 course while the DAT01 screenshot is built from the data provided by Anaplan Academy. I would have thought since they're both the starting point for the model buildout in L3, shouldn't the grand-totals be the same?

Kind regards,
