Checkbox command line interface does not support selecting suites

When running the Checkbox command line interface, the following choice is provided:

Select the suites to test

  a: Audio tests
  b: Disk tests
  c: Fingerprint reader tests
  d: Firewire disk tests
  e: Kernel modesetting tests
  f: Network tests
  g: Peripheral tests
  h: Video tests
   : Space when finished
Please choose (a/b/c/d/e/f/g/h/ ):

However, no matter which letters I enter, all the suites are run. Instead, the interface should provide somekind of feedback about which suites are selected and enable the user to select and unselect specific suites.
