'Type' field in adding to collection

Hi,

I’m testing out WebLibrarian for our small school library and am trying to add books (succeeded in getting the bulk of the books entered via a CSV file).

When I try to add a new single item to the collection, there aren’t any choices to select from in the ‘type’ field. Can’t add a book as it tells me ‘type is invalid.’

Tried this in Chrome and Safari for Mac.

Any suggestions appreciated
