Different Price format on the product list pages and detail pages

[fmlk4u]

In the language file I have modified in the com.virtuemart.ini file (for VM 2.x already

COM_VIRTUEMART_PRODUCT_SALESPRICE="Verkoopprijs (incl. 21% BTW) " And on the new Joomla 3 plus VM3 website on the pages showing the products in a category, the pricing format is correct

See for example: http://staging5.keyboard-centrum.nl/nl/winkel/digitale-piano/home-piano

But on the detail pages, e.g. http://staging5.keyboard-centrum.nl/nl/winkel/digitale-piano/home-piano/nu1-detail the pricing is without (incl. 21% BTW)

With Firefox web inspector both pricing "strings are seen as "vm-price-desc". So why are they not the same??? 

Thanks for the solution. Regards, Fred
