You have a font conflict on your machine. Clear your font cache, you must have another font conflicting. The whole family loads for me, and shows in Illustrator.
There are many products to clear your cache the one below is free for mac
You can also find and delete all your .lst files, or use font doctor or Font Explorer X Pro
