Wrong elevation shown in route selection screen

 Is there something wrong with the elevations shown in the screen where you can select your route?

The real elevation is 32m. Here are the results of today (2 laps)

I noticed this problem also last week on a different route.
Watopia seems to be ok.

Likewise the Surrey Hills route and some of the others give slightly different elevation readings than advertised.  Not a massive issue in reality.
