Need help with 3 issues

Hi. The reset (Сброс) button does not remove all filtered requirment and does not gets all products. How to fix it?
Second I do not get “No product found” text when filtering and finding nothing. What is the problem?
Third How can I get all categories of the product when I am on any of the category page? It shows only child categories of the parent category.

Thanks in advance
