Synchronize Table data with a whole different structure - mysql

Question

The goal is to synchronize the customers data and his table structure to our table structure.
The table structure is the following:
CREATE TABLE IF NOT EXISTS `BildSerie_W2L` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`BildserieID` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,

`BildKod` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
`AvdKlassID` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
`Status` int(11) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=24 ;

The goal is to take the data in "BildSerie_W2L" and populate it in to image_series.
My query looks like this:
SELECT `BildSerie_W2L`.*, `classes`.id, `image_codes`.id as ImageID, `Elever_W2L`.Förnamn, `Elever_W2L`.Efternamn
FROM `BildSerie_W2L`
INNER JOIN `image_codes` ON `BildSerie_W2L`.BildKod = `image_codes`.code
INNER JOIN `classes` ON `BildSerie_W2L`.AvdKlassID = `classes`.class
INNER JOIN `Elev_Bild_BildSerie_W2L` ON `Elev_Bild_BildSerie_W2L`.BildSerieID = `BildSerie_W2L`.BildserieID
INNER JOIN `Elever_W2L` ON `Elever_W2L`.X_ElevID = `Elev_Bild_BildSerie_W2L`.ElevID
WHERE `BildSerie_W2L`.Status = 0
However it gives back duplicated results and not all the data in BildSerie_W2L...
