Notice: Undefined index: field_talent_name in views_plugin_style_table->sanitize_columns()

I got the error message below when viewing a view.

Notice: Undefined index: field_talent_name in views_plugin_style_table->sanitize_columns() (line 150 of /home/abc/abc.com/sites/all/modules/views/plugins/views_plugin_style_table.inc)

The strange thing is I don't have a field call "field_talent_name", and I have checked in my mysql table, there is no such field exist. I am using the "view_send" module in this view( https://www.drupal.org/project/views_send ) but I don't see this error is related ? please advise. Thank you
