Resolved and here is the solution :

Update to the Visibility (Assigned permission field on Post, Albums, Listings etc.) field where you'll decide whether your content creation is visible to the public, friends, relationships, groups or spaces. This was solved with the help of @LeonidS and I think a lesson learned of how the system really work sometime mistaken for a technical problem. In studio under settings is "Hide post to context for module in privacy field" that tweak the listing of whatever assignment it be groups or spaces you wish to see or not. Wish we could document this in a knowledgebase for future reference.
