Filter Issue

Hello

We are experiencing several issues with your product filtering plugin (Pro Version) on our bookshop website, which we need your assistance to resolve urgently. Below are the details of the problems we have encountered:

1. Category Filtering Issue: We have a hierarchical structure of categories, with parent and child categories. When a parent category is selected, it is not possible to filter by any of its child categories without first deselecting the parent category. This behavior is confusing for our customers, as it is not consistent with typical filtering logic found on other websites.
2. Search Page Filtering Issue: The filter functionality does not work on our search results page. For instance, when a user searches for “encyclopedia” and the results are displayed, selecting a filter (e.g., age group 5-7) does not narrow down the results to match the selected filter. Although the filter appears to be checked, it does not apply the necessary filtering to the displayed products.
3. Series Page Filtering Issue: Filters on our book series pages are not functioning at all. Despite the filters being visible and selectable, they do not affect the product listings as intended.

Attached, you can find screenshots/screen recordings of the issues.

These issues are significantly impacting our user experience and conversion rates. We would appreciate your prompt assistance in resolving these problems. Please let us know what steps we should take to troubleshoot or fix these issues, or if there are any updates or patches we need to apply.
