Can't transmog into Legion artifacts anymore?

[Marwenna-azgalor]

It seemed from other reports that most of them were fixed, but not ones that use offhands. Which item were you unable to transmog?

Unable to transmog staff to 1-handed Artifact appearance (Warlock)

When I click the button to apply a skull of the man’ari appearnace to a staff (from the legion artifacts category in the transmog menu), it makes the sound, but doesn’t actually apply the appearance or take my gold.
