Disable auto-English product name

[Vosteen]

Hello,

 

In our store the default language should be German, but also Englisch is available right now and some others will follow.

 

When I import some products, the description-language is of course German.

But Prestashop always sets an English default product name that is just "product".

 

So how can I change this? I'd rather see this field empty than having every item named "product" :/
