"Discerning the Transmundane" - Can't place lexicon on receptacle

I've started the "Discerning the Transmundane" quest, went to the Tower of Mzark in Blackreach, then tried placing the lexicon on the receptacle. - Nothing happened. Reloaded the save, restarted the game, still nothing. The lexicon is on my inventory, but I can't place it.
It might be to the fact that I had somehow lost the attunement sphere, and had to player.additem
it back. How to proceed with the quest?
If it matters, it's a level 27 Khajit, mostly one-handed and sneak.
Note: Completely sure I didn't drop the sphere. It just vanished from the inventory.
