Gpx import shows 0 miles

Hi.
My Windsport Tracker gpx imports normally work great. But just today importing a gpx file shows a single point and 0 miles.

The same gpx file is successfully opened and view by other gpx viewer apps.

Any ideas on a fix? I could share the gpx file.
Cheers
Tom

the same situation. I import from zepp application, it shows speed 0. I import old files from last year, where before speed was calculated normally, again speed 0

hi,

could you both please send me an example file at:

support@sunbits.de

if it is from Zepp, it might be there missing information in the GPX files.
I will check this.
