There is a manual step at the moment between the GPX/KML and the elevation profiles. I almost have that automated but I’ve been distracted by a another exciting, but urgent, prospect for the site in the last week. I should be finished with that very soon so I’ll get the changes out ASAP.
However, I think there are also some issues with a few of the files. I’ll need to work through those manually and see what’s causing the problem.
And you are correct, there is a problem with uploading the GPS data. The caching change from awhile back is getting in the way (I’m not refreshing the cached walk data after the upload). I’ll get that fixed up.
Thanks, as always, for reporting those issues!
