Are you duplicating a precomp in the project window, because after duplicating it, a new version isn’t automatically opened up in the timeline, you will still be working in the original until you open up the new duplicate(a mistake I make often)
There’s a great script, True Comp Duplicator, that makes complete duplicates of a compe and it’s precomps creating new links, you might want to check it out.
