The books I borrow from open library no longer seem to link in to ADE

Hi,

I joined the Open Library https://openlibrary.org/ and when I first registed they suggested reading the books on ADE.  i signed up and everything went perfect - my borrowed items appeared in the borrowwed section.  Since them I have returned these items and borrowed more, but the new items do not appear in the ADE. 

Any one have any suggestions?
