The Garmin Connect page for each ride history with my Edge 130 no longer reports elevation gain and does not show an elevation graph. Previously ride reports showed four graphs (Elevation, Speed, Bike cadence, and Temperature). Now I get only three graphs, omitting Elevation, and also "Elev Gain" at the top of the page now shows "--" instead of the gain for the ride. I did not intentionally change any settings, but must have. Please advise how to get elevation reporting back.
