Headline not showing in color section

Hi, I have created a new site at http://www.nicologic.com. If you go there and check the color section called “Termine” on the main menu, you will see the parallax background image but not a headline, sub-headline and text I have set. The strange thing is that it was there until I updated to 3.0.5 today (I am not entirely sure though if it really happened with the update. The text was there yesterday and disappeared today). On the site builder page everything is set correctly and the way I want it to be. If you check the element with Firebug it looks OK. If you mouse over the spots where the text should be the cursor even changes. But you cannot mark anything. The text just doesn’t show.

I have deleted the headline element, text element and even the color section. I have used another background image. I have changed the color settings of the fonts. Nothing helps. And the strange thing is: all other color sections on this website have the same settings and they work fine. Just not this one. Would you have any idea how I can fix this please?

Thanks a lot.
