Can't visualize 3d data of a Skydiving experience

Hello,

I have recorded a parachute jump and noticed some anomalies:

  • The track correctly recorded the altitude variation but does not display it in 3D, even if I try to export the GPX data to other viewers.
  • The speed seems to be calculated only in 2D, whereas it should be calculated in 3D. Is there a way to correct this?

GPS data here: drive.google.com/.../view

Thank you,

Alessandro
