I guess it's possible that the GPS data file on Bangle.js is actually fine, but it's the download to the PC that is causing the issue? I think there may have been some issue if the download took more than 30s...
If you go into the GPS recorder app in Bangle.js and look at the track, how many 'records' does it say there are? Does that tally with the amount of records there are in the KML file that's produced?
