Worlds, gold versions or otherwise, are not Origin content. It doesn't matter if Origin thinks you have these things or not, Origin is only a purchasing agent for some of them. What is important is what the TS3 Store Site says, and this all has to be under the same user account credentials (email address/password logins are shared between them).
Origin only manages the base game, Expansion Packs (EPs), and Stuff Packs (SPs), not TS3 store content, The only reason Origin became a purchasing agent for store content that can be bought with money rather than points (you get a code to redeem at the TS3 Store, not a download) is that somewhere along the line years ago they took away the ability for the TS3 Store itself to do cash/credit card transactions.
If you are not getting the TS3 Store content showing up as owned by you and downloadable from the actual TS3 Store, then something is wrong that really only Customer Support can straighten out. Note that if two or more accounts of yours have ever been merged together (if this is the case), then purchased TS3 Store content does tend to get lost along the way but the Customer Support agents are supposed to provide a warning if that is about to happen.
