In case you imported images before adding the lens profile: Try "reload EXIF" in the lens correction setting for the pictures.
(If that works and you want to apply it to many images: "fix" one image and use it to "copy selective image adjustments -> lens correction" and paste to all other photos taken with the 17/1.8 (use "metadata browser" + "link to catalogs" + "photo info -> ..." to find all of them, then "select all".)
For images imported/loaded after adding the lens profile, it should be automatically recognized.
