Assigning one Delirium passive removed another, can't allocate "You thought you were free?"

I assigned the "Grand Mirror Chance" passive after "I see your true nature now!", and it at the same time removed the "I'm not alone anymore!" point?

Also, I haven't been able to allocate "You thought you were free?"; might be related.

So running the next map and being assigned another quest point:
- I think "I'm not alone anymore!" was allocated again
- But when I then allocated "Is that the best you've got?!", it again got de-allocated (I guess only visually, then?)

I don't have any 'free' maps left anymore to experiment further -- because of https://www.pathofexile.com/forum/view-thread/3943239 i don't dare run the maps of the quest line, afraid to brick the quest (I only have 4 maps left to try to reach 100% delirious, from 10%)
