El import de feature sólo funciona para 1 producto

[prestabbr]

Hola,
 
Llevo 6 horas peleándome con este problema... Tengo que importar 400 productos a mi web, para ello me he creado un CSV de prueba con sólo dos productos. Se realiza correctamente pero sólo me asigna valores a las features (características) del primer producto, para el segundo me sale en blanco.....
 
Estas son las dos líneas que estoy intentando importar, son dos vinos cuyas features son el volumen de la botella y el tipo de vino.

The albari_o grapes from which Abadia de San Campio 2007 was made, which were picked between 1 and 3 October, came from the plots at Goian (Argallo), our highest vineyard, where the humidity is lower, the temperatures are cooler and ripening is slower. These conditions provided a wine of great aromatic intensity typical of the grape variety, with hints of ripe white fruit. Golden Delicious apple and pear supported by pleasant notes of citrus. With a good breadth and balance of flavours, the wine is bright and fresh, with a certain tartness reinforcing the sensation of freshness.;albarino;;;;campio;In stock;Out stock;1;;1;http://www.miweb.com/img/products/13584.jpg;1;Volume:75cl:14,Type:White Wine:62;0;new;4

This wine is elaborated starting from the free-run juices of the native quality varieties from the O Rosal Valley, located on the Galician riverbanks of the Mi_o River, very close to the river mouth in the lands of La Guardia, in front of the neighbouring Portugal, under the Designation of Origin from Rêas Baixas. Its prominent personality is the result of a combination of grape musts from the legendary Albari_o variety (approximately 70%) with those of the singular Loureira and Cai_o Blanco in the most adequate proportions. The result is a wine with an interesting complex mix of aromas, combining white fruits, orange pips and peel with fresh balsamic notes, supported by subtle floral and mineral hints.;rias baixas, white, terras gauda;;;;terras-gauda;In stock;Out stock;1;;1;http://www.miweb.com/img/products/395.jpg;1;Volume:75cl:66,Type:White Wine:62;0;new;4
