I use GE 7.16.0 on Mac, there are lots of problems, for example:
1. when I connect the Edge Explore 2 to the computer and sync with Garmin Express, then GE doesn't see any of the datafields I already installed and use. It displays them (so it knows I did have them in the past), but there's no settings line, only the download icon.
2. even after I download them again, (then I even synced again with GE) the same: no settings link, and it thinks the DF isn't installed, so it only has the download icon.
