An anchor not working when accessed from different page

Hi, at my page: http://crownfood.cz there is an anchor #kontakt which works just fine when accessed from its (main)page When you try to access it directly ( http://crownfood.cz/#kontakt ) or from the menu on the subpage (jídlo) it just stops in the middle of nowhere. Could you have a look for me? Other anchor links work perfectly and honestly, I don't have a clue.
Thanks in advance
Karolina
