Hi Imogen. Welcome to justanswer.
Are you dropping the gpx file to NEW FILES FOLDER in the garmin drive?
Transfer them on NEW FILES FOLDER instead.
Click on the Garmin drive to open the folder, you should see a tree with a folder named ‘New files’.
Drag your saved GPX file into the ‘New Files’ folder, your PC will transfer the file to your Garmin
Try that and see if the issue is still there or not.
Go to Training-Courses and choose the course you transferred.
