Elevation bugs in Basecamp 4.2.2

In Basecamp 4.2.2 :

- WHEN I CREATE A ROUTE AND MAKE A TRACK FROM IT, the total ascent and descent displayed are : 0
- when I select all the trackpoints of the created track, the total ascent and descent displayed are still : 0
- when I select all the trackpoints of the created track EXCEPT THE LAST ONE, the total ascent and descent displayed are correct (or at least not 0)

- Wen I transfer a track from my Etrex 30 and SET THE ELEVATION OF THE TRACK TO THE ELEVATION OF THE MAP, the elevation of each point IS modified, but the total ascent and descent displayed are NOT UPDATED
- when I select all the trackpoints of the track EXCEPT THE LAST ONE, the total ascent and descent displayed ARE UPDATED
( so that there is a significant difference between the total ascent and descent displayed WITH or WITHOUT including the last trackpoint! )
