Only half of my track is uploaded to my device as a route

I have been on a 3.6 mile walk today and created a track using my Etrex 25. On returning home, I have connected my device and converted the track to a route on Basecamp.

On Basecamp on the computer the route looks correct and when I select the route it says it is 3.6miles. When I disconnect my device however and go to the same route it only shows half of the route and says it is 1.8 miles. 

Is it something I am doing or does this sound like a fault ? I have converted many tracks previously using exactly the same method without issue.

Thank you
