Just got back from a week on the Rochdale Canal between Sowerby Bridge and Littleborough. Kept a GPS trace the whole way so I've been able to fill in missing sections. However, I also waymarked every bridge and lock that I went through and noted all the names and numbers, but these waypoints are not showing up in Potlach when I edit the GPX. Any ideas why? I though it might have been a lack of timestamps but I tried again to upload the GPX, having edited in timestamps for all the waypoints and it still isn't showing them. I'm sure I've got this to work before!
