Playstation Plus supports automatic upload of PS3 save data (for compatible games) to online storage, but there was never any automatic download of save data from online storage. Playstation Plus won't replace save data on your PS3 hard drive with the online copy without prompting you, and will only do so if you manually copy it using the option menu. Online storage has its own folder which appears at the top of the PS3 Save Data Utility, but your local PS3 save data is also in the Utility further down in the list. You might need to scroll down to see it. You are probably looking at old LBP1 and 2 save data that was automatically uploaded to online storage the last time that you subscribed to Playstation Plus.
