I had same kind of pbs. But in a different way...
I had 8 scrolls in my inventary but only 5 shown in the storyboard.
I see that It takes time to update numbers on the storyboard. Then after 5 minutes it was updated.
Same things happens this morning fighting monsters. I fight 5 but storyboard was still showing 0/10 mounsters. Then I finished all energy and had to go working. When I check later finally it was update ! 5/10 mounsters.
Maybe you have to wait inventary and storyboard will take time to update ???
