make sure your descriptions have no "hard line breaks " or " carriage returns"..

try this, in easy populate delete all your descriptions..

Make a new description that's longer than 15 characters (since that's the google min required, and less than 70).

Just put this in excel and auto complete to the bottom
"my new 15 plus character description"

If it works without your descriptions then you probably have some funky characters in there or something..
