This is still an issue, even on the PTS, which was recently updated. Scalecaller and Fang Lair do not show up in the list of styles at crafting stations.
Kaivalya is partially correct. There is something unusual about these 2 motifs- they do not show in the list if you do not know them. On my crafter who has learned everything, they are where I remembered them being, between the Clockwork City and the Summerset motifs.
Edited to add: I think this behavior is similar to the crown store only motifs.
