cant find user sounds on H6 HS3

i downloaded some sounds with "vst sound archive "extension, from the “user content” sub forum page.
i double click them and it registered to the halion library manger and it shows there,but i cany find them in H6 or HS3.
is there also another way to load them without register them first to halion library manger ?

Click the blue/orange button that says “All Instrument Sets”, near the load tab.

Do the libraries not show up there?

it doesn’t appear in H6/HS3 content set(or in the preset search box)
the only place i see them is in the halion library manger,but seems it does not link it to halions mediabay or content set
all the factory and other purchased libraries (Hso.Dark planet etc… are there)
