Sintax error in contentType.features.field.inc (in a entity type)

When I generate a features with a content type, I have a error in the file of the content type.

I thing that is because the entity type use a different sintax for represent the array.

The error exactly is:

The wrong way:

'entity' => {
            "item_id" : null,
            "field_name" : "field_valores",
            "field_usuario

" : { "und" : [] },
"field_fecha" : { "und" : [
{
"value" : "2015-01-01 00:00:00",
"show_todate" : false,
"timezone" : "Europe\/Madrid",
"offset" : 3600,
"offset2" : 3600,
"value2" : "2015-01-01 00:00:00"
}
]
},
"field_valor" : { "und" : [] }
},

The correct way (I alterate it):

          'entity' => array(
            "item_id" => null,
            "field_name" => "field_valores",
            "field_usuario" => array( "und" => '' ),
            "field_fecha" => array( "und" => array(
                  "value" => "2015-01-01 00:00:00",
                  "show_todate" => false,
                  "timezone" => "Europe\/Madrid",
                  "offset" => 3600,
                  "offset2" => 3600,
                  "value2" => "2015-01-01 00:00:00"
                ),
              ),
            "field_valor" => array( "und" => '' )
          ),

¿Any solution? I searched about it but i haven't the solution. For the moment, I change the file manually, but i don't know exactly when i have to modify the module.

Thanks
