New Post: Only 1 Product after adding a new language

Hi there!

Sure I am missing something.
I have added a new language to the dnn install (nl-NL) and proceeded as adviced here (https://nbstore.codeplex.com/discussions/360175) for activating the language in nd store

But there is only one Product and no category after doing the stoe validation with Fix checked

I think it has somethingto do with my dnn.default language and nbstore-merchant.culture but I am stuck with trying how to fix this

my merchant.culture is de-AT
the default language for the portal in DNN (/Admin/Languages/Site Default) is en-US
the installed locales in DNN are de.DE, it-IT, en-US, hu-HU and (new) nl-NL

Can anybody please advise how to proceed or what I can try next
thanks!
