@EightBitz: Part of the issue may be "non-standard" or "new" elements.
Some of the tags referenced don't look familiar to me. I know some were added with Ultimate Magic, and "Ruse" specifically was added with Ultimate Intrigue. If some of the others are from, say, the "Legacy of Dragons" Player Companion, there's a good chance that it is obscure enough not to be known to whoever put together the Pathfinder Structure. Likewise, Anti-Paladins having spells above 4th level is probably from a specific Archetype, and may not be known widely.
If any of the unrecognized items are from third-party publishers, their inclusion in the official standard Pathfinder structure is questionable, as well.
