Maybe I'm misunderstanding something here, but isn't that where you want your sediment to be? At the bottom? Sounds like you just got some drop-out after your first racking, which is normally expected.
How clear is the wine itself? Even thou Pinot Gris can be a pretty deep shade of gold, it still should be perfectly clear before bottling. If you look through the carboy at a candle flame or other small light source on the other side, you should see no haziness whatsoever.
If it's hazy, give it more time like the directions said. If nothing has improved after 7 more days, and you've already sufited and fined your wine (and your sure the wine is finished), you could just try stirring the lees (sediment) at the bottom back up into the wine and waiting another week. If it's still not clear, you may just want to contact the wine kit's manufacturer for advice, or try different fining products.
You know you have a serious clearing problem when your wine has been freshly racked weeks ago, there is no sediment at the bottom, and yet a haze persists in the wine.
