I'm having issues with a couple different word walls. The first is Volunruud, where the wall makes the sounds and chanting, except no words light up and I learn nothing. And I do not have the word already learned. It is the aura whisper one. The other wall is in Valthume, where you find the other aura whisper word, this one was learned but never showed up in my list of shouts to unlock. So right now I only have the first word of Aura Whisper, and I cannot learn the other 2 because of bugs.
