Hi,
Thank you for your feedback.
The filters can be displayed with a HikaShop filter module. A module can be displayed on any page of the website, even of pages without a listing of products displayed by HikaShop in the main area.
A filter with the "dynamic display" setting activated will get the minimum and maximum values from the current listing of product on the current page. So if you display the filter on a page without a listing of products in the main area, it has to fallback on the minimum and maximum values configured in the filter settings.
So both options are not contradictory and have both at the same time can be necessary in some cases.
In your case specifying a min and max might be superfluous. In that case, just set a min of 0 and a max really high and they won't be used.
