The logic regarding this addon is wrong. Please adjust it so that it works properly.
When a user is searching for something, he wants to find results for a specific product. Becouse that is what he is looking for. Like a car. He doesn't want to get 1000-10.000 ads from paper, pencils to crane or houses when all he wants is just a car.
So, if we have this block added in left column, in each type of categories, and a user is using it, he MUST GET only listings from the category from wich he used the search by distance block.
