Garmin 310 Data Issue (Read 205 times)

Something strange on my last 2 runs/uploads.  Everything progressed normally and all data appeared in the fields (distance, time, HR, splits, starting time).  While I was editing (putting notes, temp, equipment) the time and distance disappeared.  Splits and starting time remained.  

I had to manually add the distance and time back. 

Any ideas?  THANKS!!
