There are some works showing up as Unrevealed in the collection. I've been told I can fix that on the mod end by unapproving and reapproving your fic/art. If your gift, or your work, is showing up as unrevealed, comment below with your username (and title of the work, if you're the gifter and not the giftee), and I'll see what I can do! Comments are screened, so only mods will be able to see them.
