Menue disappearing on some created sites

Hi folks!

I have a problem with the minimatica theme which i am running on my site.
The Menue which is shown under the slider of the homepage, does not show up on every page/category which i’ve created.

So now im facing the problem, that the menue is not shown on every page at the bottom.

it is function on the sites “contact” and “archives” but does not work on the other pages or categories.

i’ve tried and searched for hours but cannot figure out why this happens.

maybe some of you guys have some ideas how i can resolv it ?!?
