Quest: A Descendant of the Ancients - Unable to complete

On this quest you need to spend energy to Learn to First through Fifth Knowledge of the Kamasylvian Ritual. I have clicked and ran through the 5 NPC's for the Knowledge and can't complete the Fourth. The NPC no longer has the option for me to complete this part of the quest. I know I spent the energy when the quest was available yet the game didn't give me credit. As this is part of the Main quest line I can lo longer advance this character. I Forfeited the Quest only to restart it with all components showing completed except the Fourth.

Please advise me on how I can fix this. Can't seem to find anybody else with this issue or any that have heard of it.
