I am trying to import a straightforward Excel file that has 4 indicators, 4 dates, and several countries.  

When I import, no matter what dates I put in or what format the dates are in (number, text, date), the dates are all stripped and replaced with "2007" following the import.  My dates happen to be month specific.  I thought perhaps that was a problem so I experimented, replacing all dates with just years (fake, of course, which is undesireable).  Still, every year got stripped out and replaced with "2007" (which isn't in my data set).

I've also run tests where I structured my source data to look the way it's supposed to after the import (date on one row, one column, associated indicators for each year in next column over and one row below), but the dates are always stripped out and replaced with this mystery year "2007".  I even redownloaded the original file, StatPlanet_data_editor.xls, thinking the copy I had been working with may have gotten corrupted.  Same result.  I've tried also saving my source data as "xls" instead of "xlsx".

I'm running out of ideas of how to add/format dates and the source file differently.  Data gets correctly associated with countries and indicators in the import, but without something so basic as dates, it's a mess.

What could I possibly be doing wrong?
