Why does CurrentApp.LicenseInformation.IsTrial always return false in the release version?

I've developed a Windows 8.1 Store App and have integrated code for converting a trial to full license. When I check the LicenceInformation.IsTrial property, it always returns false in the release version. Here's the method from the License class I created that accesses the License Information:

private static LicenseInformation _information;
public static LicenseInformation Information
    {
        get
        {
            return _information ?? (_information = Helpers.IsDebugMode
               ? CurrentAppSimulator.LicenseInformation
               : CurrentApp.LicenseInformation);
        }
    }

I've submitted the app to the Store but nobody can purchase it because the it appears to be already purchased when my code checks the Information property. Why would this happen?
