Comments format is wrong/buggy

Hi,

I’m running 2 Blogs from wordpress. The installation was absolutly easy (for me as a “normal”). But I have one problem with the format of comments. Look at https://www.bindestrich.net/blog/2005/08/22/das-erste-mal/#comments . And it should look like this one https://www.buellesfeld.net/ruelps/2005/08/22/zu-tode-designed/#comments . I’m using the same css-file. So, what ist wrong?
