speed field always displayed empty

[routeconverter]

I just started using this app and I noticed that the speed field always remains empty, even when obviously not empty.

It could be two options:

• Speedometer55 Pro doesn't create valid GPX 1.0
  
• Or it creates GPX 1.1 and since that doesn't support speed, Speedometer55 Pro creates a new proprietary way to include speed information that RouteConverter doesn't understand yet
  

I need to have a look at the files to analyze more.
