Zendesk Android Support SDK - getAllRequests: wrong data in wrong field

I'm using Zendesk Android Support SDK v5.0.2. When I request all tickets by calling getAllRequests function on request provider, the response returns all tickets created by me. However, the problem is that "description" and "subject" fields return the same thing although I set them differently. Both fields return the value of "description". So, the "subject" field returns the wrong data. Any comment?
