acceptedterms and multi languages

Hello.
I am working around with the registration form.
My whole site is multilangual now (eng, german) and i have only one field "acceptedterms" with no language-feature or language-param.

I want to use URL for output. but i am only able to set one URL.
I have a german menu item pointing to a single german article and an english menu item pointing to an english article.
both menu-items are connected. so are the both articles.

but when i put in the german menu-item as URL, the german article is shown for german and english users ...

What can i do?

Supply a URL to your Joomla article then use Joomla language associations to make it multi-lingual. Believe that should work.

this is what i have done ...

joomla plugin "system-languagefilter" connecting is ON

i have a connection between the german and the english article
i have a connection between the german and the english menu-item

if you want to try out:
dodge-ram.fans
click on register
click on terms and conditions
you will find the german article in the popup
i have the normal site-template actualy in the popup. so you can change to english to see that they are connected

Your terms and conditions URL should be non-SEF beginning with index.php. Example as follows.

index.php?option=com_content&view=article&id=ARTICLE_HD_HERE&catid=CATEGORY_ID_HERE

If you've a menu item for your terms and conditions (recommended to have one) then be sure to add &Itemid=MENU_ID_HERE to the URL as well.
