Purchased The Yawning Portal Module Can't create any games with modules

I purchased the Yawning portal compendium and I am trying to create a game using the Sunless Citadel module that comes in it. When I go to create a game, it shows a list of modules to the right. I own NONE of the modules that are showing to the right under where it says Recommended: Choose a module . Some of the ones showing are not even for D&D. I have scrolled down and clicked on More Modules button. Still none of my modules are showing. When I scroll down to From the Market Place none of the modules showing are ones that I own.  Why are none of my modules showing? How can I create a game with my modules if I can not see them on this list of random modules that I own none of? Help appreciated. Thank you.

Hi Zelvick! The adventures in Tales from the Yawning Portals are Addons, not modules. Addons are shorter, and can typically be added to games without causing bloat. Create a new 5e game. Once it is created, you will find an addon dropdown on the Campaign Details page, click the little arrow to be presented with a choice of addons. Your adventure will be in there. It doesn't help that the instructions say "Campaign Settings Page":

Many thanks. I will try this.
