blog dont shows short versions of posts

Hi

I am building up a new website and I have done a blog. I have two languages and entity translation. Now the problem:

I have done a blog with the standard modul, that comes with drupal. I have made a menu link for the blog and two first posts. I also translated the two posts and also the menu link. This all woks fine.

But when I am in my standard language (in this I also wrote the two posts, befoe I translated it) and click on the menu link "blog", I can see the blog with the short version of my two posts in the original language. If I change the languages to english, I can just see the blog, but without posts.

Anyway, if I click on one of the two posts in my original language and so see the hole post, then when I am changing the languages, I can see the translation in englich.

So just the "overview" with the short version of he posts I can not see in english. What is wrong? Is the modul just showing the short version in the language that I wrote the posts?

Hope someone an understand, As my website is still in maintenace mode, I can not let you see. The link for the menu point is like this:

mywebsite/de/blog/1

but mywebsite/en/blog/1 is just showing a empty blog (admins blog), anyway the english translation of the two post exist and are showed, when I choose one of them in german and then change to english.
