Not for sure what you mean. If T3 or Higher is all that shows up in your search results, then start LW and go to Tools>Options>Searching>Speed, and put a tick beside Show All Speeds, click apply.
If your getting all the different speeds in your search results but can only d/load from T3 or Higher, then I'd guess that the other files are probably fake.
