Mike, Peter,
Some cases I have same result, too, but I think it is a date conversion issue.
The month (or day) has no two digits in uploaded csv and gpx files:
ie
xxxxMap_GERHES MittsommerOL 2020 Bahn 5 PZ PXAC_Course1_2020621_82555
xxxxMAP_MapRun Challenge 20202 Whitfield Valley Score PXAS ScoreV60_202067_63517.gpx
when I use the old page, it works well:

Thank you!
