Skiing Track showing wrong max. speed

Today,while skiing, I recorded a track on my Fenix and imported it in Basecamp.
The track seems ok, while not very accurate.

In the overview of the track properties (after double clicking on the track entree) the max. speed shows 76km/h. However my actual max.speed was 91km/h as I can see in the list of points.

The strange thing is that when I delete a single line (doesn't even matter which one) the correct max. speed (91km/h) is shown.
This makes the overview unreliable, so I would like to know whether this a known issue?

(I am not sure if I can upload the track)
