Nested Filters

I am using this plugin to create filters for my woocommerce website. I have created individual product pages which display products of only one particular category ( Using this shortcode [product_category category=”category1″] ). I would like to create nested filters for these product category pages ( For example if the user selects car brand = Maruti Suzuki, then a second filter appears wherein the user can select Maruti Suzuki Model. If the user selects Toyota, then a filter should appear which lists only Toyota models ) .I have put the berocket filter group on the page which has there 3 filters – 1. Car Brand 2. Maruti Suzuki Model 3. Model Year. In the Maruti Suzuki Model filter, I have added a condition (under nested filter option) that it should only appear when the user selects car brand = Maruti Suzuki. However this is not the case as the filter doesn’t open at all (there is no condition set on 3rd filter and that is why you can see 2 filters on the URL I have provided). All the filters have been set to filter by attribute and all of them work independently (if I remove the condition on 2nd filter, it works as well). Please help me urgently to achieve this functionality as it is vital for the website that I have to provide to my client.
