Some Apostle and Ebonshadow motifs seem unknown ("Use to add to your lore library" wrote instead "Already in your library" (also some addons see the motif scroll as unknown)) but I know them (in fact if I doble click them appear "you already know this chapter of this Racial Style and I can craft item with this motif). It is quite annoying expecially searching the uknown motifs on Guild stores.
