Issue with WPML – image swatch

Hi,

I set up a swatch with images and it looks good on the German main page:https://schwepper.com/store/knaufzylinder-messing-mit-seewasserbestandiger-schliesnase-und-verschiedenen-knauf-designs-gsv-nr-391/

On the english page the images are not being shown: https://schwepper.com/en/product/thumbturn-cylinder-seawater-resistant-type-brass-gsv-no-391/

Any idea? Thanks
