OneFS CreateChangeList API broken?

We're testing Isilon OneFS Changelist  REST API on simulator and found that the result returned is incorrect. For all the entires it returns "REMOVED" while CLI works just fine.

• • Do you know if this issue is fixed for newer versions? 
  • Is there any patch for older versions? 
  • Is it possible to identify if patch is applied or not on older versions?
  • List of versions for which this API is broken.

Appreciate you help in this regard,

Thanks,
