Product review (5 stars): Temporary Fix
Did not purchase (yet) - did what others suggested and switched track from opposite side of shelf.  How?
1. Remove Snack Tray
2. Remove Glass Shelf holding brackets from Refrigerator
3. To remove brackets , turn shelf upside down and slide bracket (both) approx. 1/2 inch thru the hole openings (be careful not to break).
4. Now swap bracket sides.
