Unable to switch direction modes in places.mapzen.com

[stepps00]

Once directions are given for a specific transportation mode, like "walking", I am unable to get directions for another transportation mode.

Steps:

1. Go to https://places.mapzen.com/id/102085387
2. Click the "where I am now" link from the "Get directions from where I am now (use geolocation) or from a specific location." line.
3. Notice that walking directions are the default
4. From the drop down menu, select a different transportation mode
5. Notice that the "Get Directions" button is not click-able
