On my main character I can't access some of the essences at the lectern, even with having a phantasmal core, all I can get is my armor pieces and arc logic. I can't pick up the essences for love and death, loud lullaby, tranquility, night terror, or every waking moment. It says I can only hold one at a time but they aren't in my inventory, and again I do have a phantasmal core, it just won't let me grab the quest.

Check the abandoned quest archive in the tower.

Hi there! This means you've abandoned them some time earlier. Go to the quest archive next to the postmaster in the tower. You can pick up all essences, that state you can only hold one at a time from there without the need of any material.
