Trying to merge two existing features and select which attributes get retained (or preserved) but I cannot change which attributes actually get preserved. According to the help (referenced here: Merge features into one feature—ArcGIS Pro | ArcGIS for Desktop ) you are supposed to click on the feature listed in the Merge window and that is supposed to put the (preserve) qualifier next to that feature but when I click on my feature nothing happens.
I see the preserve word doesn't change, but the highlighted piece seems to be preserved.
This has been fixed in Pro 1.4
"Preserve" moves with the highlighted row.
