[SOLVED] View with Grid format: Title of first entry doesn't show up in other languages than English

EDIT: A database update seems to have fixed the whole thing.

I have a view that uses the grid format and a grouping field.
Interestingly, the title of the first block (with the others it works) in the grid never shows up, even though the content exists!
It's difficult to explain, so please have a look at the picture:

It does not show up in the German page, but in the Englisch version it actually does.
but i didn't enable translation for this content type so i don't understand why it should not show up in any language.

(I posted an issue in the views-module-section before, but was told to ask at i18n)
Thanks for any help! :)
