Storylines & Creator credits and Item Descriptions are basic info Express, Pro, Archive users get with weekly content updates.
I assume you have them checked when you update in the main CB software OR in CB Sidekick?
BTW, the update settings you set in the main CB software aren't used in Sidekick and vica-versa. Maybe worth double-checking your update settings in both.
As an example issue to track if its working for you, do you have all the storyline, writer and artist info for Fantastic Four (6th Series) #48?
