Add a new race-->Unmatched

[calvertcruz]

When clicking the add button for the first racer, other racers disappeared from the unmatched box. After clicking the add button for the second racer, all unmatched racers disappeared from the unmatched box. Strangely, when clicking the 'x' button on the previously selected racer returns the previously deleted racers to the unmatched box. Also, if you 'save and add another race' the racers re-appear.
