Hello Craig,
It seems you copy excel table with embed method into PowerPoint. It only shows 1993 to 2010 columns may occur if we only copy and paste this area, Could you try to copy and paste the table again with 1993 to 2013?
In the open object that shows 1993 to 2013, copy the area of 1993 to 2013 and paste in the presentation file again, what’s the result?
You can also try to paste as a picture to get what you want.
