Global products not adding to categoreis

hi,

i am trying out the multisite with global product list.

1. i add a product in my test5.marketplace.com multisite in categorie "camping"
2. The product shows up on my main site marketplace.com on home page.
3. Product is not showing on the mainsite marketplace.com in categorie "camping"

any ideas why? and also the multisties have the same categoreis as the mainsite (gridmarket) is all cloned with "New Blog Templates"
