.tpz files import from client

Hi,

when i wanted to import only specific namespace and its objects to my QA environmnet using file transport from client, why does it take all name space defination? i did select only namespace i need and objects under it;

but when i see the imported objects in QA; it has all names space defination, which i dont need (though the objects are not there) but defination is there.

is there any way i can take those off?

or only option is to delete namespace at the development? and re-import it?

Thanks.

Prema
