1. When I click a brand, all other brands in the filter disappear, even with checkboxes enabled. So this filter only operates as an OR filter. Please advise how to make AND work.
2. How to increase the size of the brand images? (“Large” is still too small…)
Actually, the same behavior is observed with other filters as well. AND functionality is not working. When one option is selected, the others disappear, until the first one is unselected/unchecked.
In general, the filter’s functionality, query type functionality comes from WooCommerce, so please check how it works on the default filters from WooCommerce with some default WordPress themes like TwentyTwenty or WooCommerce Storefront to understand is it our theme issue or not?
