eSign through web has no access to choose DocumentCloud docs?

When I log in with my AdobeID to my DocumentCloud account on a web browser I have access to documents I previously saved in there. What I am trying to do though is when I go to the eSign (send for signature) feature that I also have a subscription to... I can't choose a document that I have in the DocumentCloud. I only have options to upload, choose from a document library or some online clouds like google drive and box.

Are we just not able to select a document from the documentcloud? It seems silly we can choose from other cloud services but can't choose from our very own adobe cloud. I've looked and looked but can't seem to find the option.

Note: I downloaded the Adobe eSign Manager Android mobile app and through the mobile app I can access documents in the documentcloud. Surely I'm missing something here... please help
