I can't add TCGA data from a query to my project

I've joined today as a beta user and started a project, but once I do a query and pull up a list of files, I'm unable to highlight them either on the query map or the list of files in order to add them to my project for analysis. Is this a bug or am I doing something wrong? The help page indicates that I should be able to click on a path to highlight and add those files. Thanks!
