Anyone had this issue with SportTracks software?
 

I'm using the software for my Garmin Edge 305. One day last week I went to upload my rides and it says I road over 1300 miles in ~50 minutes! Average speed of 1600+mph. Even the map shows the general outline of where I rode but the loop was literally filled hundreds of the blue directional arrows. I know I wasn't doing Mach2+ so I uploaded into the Garmin Training Center software and it read normally. SportTracks has worked fine for my rides since but its kinda messing up my long-term data tracking. Any ideas?
