On a 2021.0 and 2021.2 system, exporting to Excel from a list box results in the cell formatting applied being off by one column whereas on a 2020.1 system, the cells have the correct formatting applied.  On the 2021 systems, this was observed when exporting from the Invoices tab's list box in both Customer Maintenance and Vendor Maintenance and when exporting from the Transactions tab's list box in Item Maintenance.
