Wrong link on https://doc.zih.tu-dresden.de/software/scs5_software/

https://doc.zih.tu-dresden.de/software/scs5_software/ contains a link to https://doc.zih.tu-dresden.de/software/modules/#lmod-an-alternative-module-implementation, however the page does not contain a paragraph with such a heading. Is the link-check broken? Is there some advanced link-checking required?
