'Sort By' drop down has a problem when coming back to the default sort

[cas]

On the category layout page, the 'Sort By' drop down has a problem when coming back to the default sort order.   When changing the sort order from the default order, and then coming back to the default sort order, the page is blank (no products are displayed).   Give it try here: https://www.hairextensionsfair.com/shop

Updated to VM2.0.1.d and it works correctly now.  Thanks.
