Hi, I've had this happen to me before, and the reason for this was that the edit session actually is placing you at the trace start point, because the trace actually starts at home. The cause was having the GPS automatically start tracing when turned on, this on a a Garmin etrex/Legend/Vista with extra SD Card storage maybe, then uploading the GPX trace from the SD Card. I had turned the GPS on at home to check the batteries, then switched it off. Transit to the mapping location and switched on to start tracing. My Garmin will store it as two tracing sessions on the internal memory, however the SDCard GPX version only has one session/file per day, so the start of the session is at home, with a subsequent jump to the point where you think you started. Uploading this GPX trace (from the SD card - the 'one-GPX-file-a-day' session to OSM will result in the behaviour described. I can't tell if this is the cause of your problem, but it was the cause of the same symptoms for me - hope this helps! The workaround for me was to transit to the tracing session, and erase the days external SDCard GPX trace file when starting, it will be immediately re-created by the Garmin and tracing start from where you actually want.
