Custom Filter for each category

Also, please help to fix the filter issue.
When I choose a category for example Watches and choose the brand name if there is no product on this choice on the result page filter shows only the product category (in this example Watches) and brand names, gender, and price range filters are not showing. It’s working again when users clear filter options.

I think we have some misunderstanding here.

1) I don’t have any cache plugins.
2) All products have attributes (at least gender).

Let me explain to you again: I have products with attributes in different categories. The main category is Watches and Accessories. (links added to Private content)
When a user clicks a link that redirecting to the Accessories category and chooses a brand name (for example Aerowatch) that doesn’t have Accessories with this brand, it’s loading a new page and it is written: “Product not found”. It is normal but, on loaded page filter has only one option to choose: “Categories”. Other filters are not showing(screenshot attached). The filter should stay with all options not try to search again. The question is: How I can fix this issue?

The second question is: How I can show on the filter of Categories link only some brand name choices which ones have products on Accessories category. If I need to clarify the question: How I can create a different filter for different categories?
