Category Problem

Hi together,

ich have a small problem with multiple categories.

The Problem is i have Properties with 2 assigned categories (Häuser / Aktionshäuser) and a SubMenu Link thats linked to one of them categorie.

But if i click on the Property in the subNav Menu link, the &Itemid= variable is changed to the parent Nav ID.

Explained in german

Navigation:

Häuser (parant Nav linked to the Häuser categorie) &Itemid=115
- .............
- .............
- .............
- Aktionshäuser (subNav linked to the Aktionshäuser category) &Itemid=446
- .............
- .............

an the Property in this listing is assigned with the parant ItemId (&Itemid=115) and not with the subNav ItenId (&Itemid=446).

Cann anybody explain what`s wrong?

THX

sorry this ist a double plz delete it
