Currently, there are a lot of errors when Views tries to render a preview using the lineage nested plugin, and the preview does not match what is actually rendered. See previous issues:

#795954: warning: extract(): First argument should be an array in lineage_handler_field.inc on line 68
#783488: stdClass error
#795996: Fatal error: Cannot access empty property in views_plugin_style_lineage_nested.inc on line 203
