Adding spells only shows core rules, 2014 expanded rules, and homebrew.

I am in a campaign with 15+ books shared. I have checked that the content is shared and my character is in the campaign. When i try to add spells it only shows the options in the title. I've tried leaving and rejoining the campaign, nothing

i was looking for summon greater demon. i am a level 7 warlock. i can see a long list of 4th level warlock spells on the spells page on the regular website and see the details of summon greater demon there, but when I go to my character sheet under spells and try to add spells there are only 9 options for 4th level spells. Under "filter by source options" it only shows the three categories in the title.

... they dont own that book. Sorry for wasting your time :/
