Since the SW 7.70 update (or possibly further back, I haven't tried editing an activity since last summer until now), I have been unable to save any changes to activities adding a CONNECT IQ data field. The default (built-in) fields all work and save, but not C-IQ ones. Any activities edited from months ago with the C-IQ data fields still work and display properly. However, any new (custom) or existing activities that I edit the settings for and try to add a data field from C-IQ show the change has been set, and also show "CONNECT IQ 1/2" in the "SCREEN 1" edit screen after adding. When I back out of the edit settings screen, and go right back in (or start the activity), I can see that my changes were not saved.
