In some cases, when the local sales tax mod is used, sales report shows double the tax collected in the Goods Tax column. Working on tracking this down.
(Latest Sales Report, Latest Zen Cart, PHP 8.3, but this bug was also present in the older non-encapsulated Sales Report.)

** Update: sorry, this is a bug in Local Sales Tax - Sales Report is correctly reporting what's in the orders_products.products_tax column, but that amount is incorrectly doubled.
