Can´t overwrite Breadcrumb by path breadcrumb

Hi,
I set a breadcrumb for a content type. For certain child-pages in this content-type, I want to set an individual breadcrumbs, but the breadcrumb set for the node-type never gets overwirtten by the path-settings.
I also set the weight of paths breadcrumbs as first, but it still is not showing any effect. In general the path-breadcrumbs work, but they always get overwritten by the content type breadcrumbs when those are in effect..

Am I´m doing soemthing wrong. Is it not possible to overwrite node-breadcrumbs?

Thanks for any help
