Listing Active Members of Current Group in View pane (OG 7.x-2.3)
In retrospect the answer was rather obvious. When you migrate from OG 1.x to OG 2.x, the views associated with OG do not get updated. So they have "missing/broken relationships." For most of the view panes it was easy to fix by going to the view page and under the "edit view name/description" drop down, there is an option to "Revert View". Choosing this fixes the views that come with OG because it "reverts" the view to the updated OG 2.x code. Custom views have to be rebuilt.
