when a user selects one or more products, the selected product counter is updated correctly (e.g., 1/10 Selected). However, after changing the Vendor and Reference, the previously selected products are cleared, but the selected product count is not reset. As a result, when a new Reference with a different number of products is loaded, the selection counter displays an incorrect value (e.g., 1/5 Selected even though no products are selected). If all five products are then selected, the counter incorrectly displays 6/5 Selected, resulting in an inconsistent and incorrect product selection count.
