Map Visualization: Cannot copy marked items

Map Visualization: Cannot copy marked items, button is grayed out, and Ctrl+C doesn't pick up marked items either



I was able to do this in other .dxp files of the same nature, but this one has quite suddenly stopped working as far as copying marked items out of Map Visualizations goes, it used to work.  I can still copy out of other visualizations in this .dxp file, but not map visualizations.  I have saved, closed and reopened this file and still am experiencing the same issue.


I have tried this with multiple data tables in the map visuals as well.  Shape files, csv files, and excel files.  All yield the same issue, in this particular .dxp file.
