Leider is die Dutch sprache schwer fur mich :? ...
So, I will answer in English. As a theme developer it is very hard to make the theme compatible with all the different extensions, and having even different versions of extensions in different languages (which should only differ in the text itself), makes it even worse.
Still, I will try to find out what is happening, and if can find a solution, it will be incorporated in the next version... No garantees whatsoever though, this is free 'software' and my spare time activity...
