Hi.
1) Using these filters doe not update the product counts similar to the way using Attribute Filters does. When the customer selects an attribute to filter by, the other attribute filter’s product counts are updated (and even removed from the filter list if their count is now zero). So, when selecting a brand, using the price slider, or selecting a stock status, it should update all the other filters and product counts too.
2) Also, in the reverse situation, when an attribute filter is selected, the brand and stock status filters’ product counts are not updated.
3) The Brand and Product Status filters appear to include ‘Hidden’ products in their product counts. They should only include products set to ‘Catalog & Search’ or ‘Catalog’.
