Do you mind sharing with us your current implementation so I can set it up locally and test the described behavior, as this sounds like a not very common scenario - there should be no reason that you won't get the newly created albums through the API, do you mind running the project in debug and checking when the code executes whether the new items have been included, if yes, then maybe it's got something to do with the way you are populating the drop down list, that's causing this behavior.
