Where did the workout run splits go in activity app?

I have Apple Watch 2 and run a lot only using the activity app. Have OS4.2. Recently, going to my iPhone activity app, the mile splits AND weather data for my runs have disappeared.... is there anything I can do to get these back?? I like the splits option. Went into the health data app and there is no background data behind the runs.... but for older runs where the splits are shown, all the data is available. Can someone help??
