Describe the bug
Zip files that are marked as ancillary resources (e.g., "Ancillary resource: Instructor edition") are being sorted as editable files in the collection, rather than ancillary resource files.
To Reproduce
Steps to reproduce the behavior:
Go to a book with ancillary resources in a .zip file (For example, Liberte.)
Click on "Editable" drop-down list.
See that "Ancillary resource: Instructor edition" is listed there rather than under "Ancillary"
Expected behavior
I expect that .zip files will be classified as Editable UNLESS they have "Ancillary resource" at the beginning of the label, in which case they should be classified as "Ancillary"
Adding a note that it is not just the .zip files. I have found PDF and PPT files that are labeled "Ancillary resource" but are sorting as Readable or Editable files. See Intro to Financial Accounting
