WHAT IS THE CAUSE OF THE DIFFERENCE BETWEEN THE ORDER LIST I RECEIVE BY PRESSING THE EXPORT BUTTON AND THAT LISTED ON THE PAGE?

As soon as you press the Export button on the Orders page, the current filters are applied and the most up-to-date data is transferred to the Excel environment and downloaded to your computer. If there is a difference between the ones listed on the page and the Excel file, it means that new orders have arrived or the status of some orders has changed after you open or update the page.
