DaseCamp loses laps and cadence info

I have a 410. On Garmin connect I can export files as Google Earth, GPX or TCX. I have tried exporting TCX and GPX files to BaseCamp. This works. I have then edited the data (The watch did not stop at the end of the run so all I wanted to do was delete the last few data points). I then imported the modified data back into Garmin Connect. The cadence data had all disappeared, which I can live with, but so had all the lap times. I have tried this several times all with similar results. My laptop is a Mac Air using Chrome under iOS 10.9.3 (Mavericks).
Can anyone explain how I can edit the data or tell me that it's not possible?

and if anyone can tell me how to post without displaying my email address that would also be appreciated. Ta.
