Those abilities were removed from the game. That's what they're crossed out like that. Spineshatter was replaced by Winged Glide, while Dragon Sight is just gone (good riddance.)

As for why you're not getting exp, do you have the Dawntrail early access registered? Leveling 90-100 is an expansion feature, so if you don't have Dawntrail registered you won't gain exp at level 90.
