Article Landmark label not output on front end

[amberhinds]

Article landmarks say "Landmark: Landmark" on the front end instead of "Landmark: Article" - see example: https://equalizedigital.com/accessible-firebrand-mark-alvis-and-deneb-pulsipher/?edac_landmark=I2dlbmVzaXMtY29udGVudCA+IGFydGljbGUucG9zdC05MjM1LnBvc3Q&edac_nonce=91a14aea7c
