I am working on a job that uses multiple styles of Helvetica Neue LT Pro, all of which are OpenType fonts - 25 Ultra Light, 45 Light, 65 Medium, and 75 Bold. Loaded on my Mac via Font Book, all are active. In the font list of the Variable Text Editor window in Acrobat, I can see "Helvetica Neue LT Pro" but I can't select it, let alone see any of the styles.
The 75 Bold and 65 Medium fonts are used in text boxes in InDesign CC that contain static text as well as boxes that I have tagged as variable text using the FusionPro plug-in. Neither of them show in the FusionPro Font Usage window in Acrobat and the type using them defaults to regular Helvetica when first exported from InDesign and opened in Acrobat.
