Help!: Lost times

I do two timed rides each day, and have been recording them faithfully.. when I checked over the times today, for some reason I'm showing 2 rides, both with the same time.. I'm not that consistent, so I'd say its a bug ? Is there anyway to ge the lost times back..

 Also it would be great if there was an export feature, so I could export the data to Excel.

Regards,

David
