I've added a Siri Intent to configure some widgets for an iOS app. For the parameter in question I used the "Distance" type, which is adequate as the user can add a distance goal, which should be either km or miles (that's why I can't only specify km or miles). However when in the widget configuration view all available distances are shown, even the most obscure. I can't seem to find any way to limit the available options to km or miles. What am I missing?
