Random Chapter Set 1 by Russ Hapke not appearing in my Art Librairy after purchase

I bought this addon for use in a game that i'm DMing and purchased it for me when i was in the marketplace. it shows up in my purchases and when i went to game settings and applied it as an add-on i got the message that it was successfully applied. However when i go into the game the art that is supposed ot come with the pack doesn't show up in my art library. please help. i have looked through the forums with other people having issues with missing art and have already applied fixes from them including: ensuring my browser is updated, disabling all extensions/antivirus, clearing cache, clearing cookies, and resetting the browser. none of these however have fixed the issue. i even added exceptions for 3rd-party cookies using roll20.net, app.roll20.net, roll20dev.net, app.roll20dev.net and status.roll20.net.

From reading the description it looks like these are pre-built maps. Have you looked in the maps drawer at the top of the page to see if they are already built there?

i have and they are

Hi, Marc S. Like Marketplace Modules, Game Addons do not add assets to your Art Library. In the case of Random Chapter Set 1 , you instead receive fully-prepared Pages. For more information about Game Addons, check out our  Game Addons Wiki section or our recent announcement . I hope this helps!
