When using a URL parameters for a Category Selector with "None" as the default, the url parameters do not change the default and instead just filter the drop down list. This in turn requires the user to intervene and pick the option from the drop down list ( please see image below). This is not intuitive nor does this fully achieve what the purpose of a URL parameter. Please change this functionality that URL parameters will be the default selection when configured with the Category Selector.
Thank you!
