Can't see stream. Audit shows access to stream,apps,app objects!

[gmenoutis]

On a server which I have 2 accounts with Content admin, one of the accounts (let's say A) cannot even see a specific stream(let's call it S). However, If I audit (with any of the two accounts) the priviledges of A, I can see R/P access to all of: stream S, the apps within, and the app objects within. What could I be missing?

It is not fully my responsibility, not having write access to security rules and all, but I would like to know what sort of combination could cause this controversy between the audit screen and what ia actually available on the hub.
