I'm running into problems when I try to add data to CI. I tried the drag and drop and nothing appeared in the data window. I then tried Import > Data without metadata and got Java.lang.IllegalArgumentException: unable to convert object null to RDF (see attached image). Note the second list box under "Content type:" is empty. Typing a string into this box has no effect.
