KendoInput and KendoListBox translators no longer work with Kendo 2015.1.429

I have recorded tests that utilize the KendoInput and KendoListBox translators to execute steps on Kendo controls in our applications (open combo box, select items, etc.)  These test were working as expected with our app running Kendo version 2014.3.1119.  However, since updating our application to use Kendo release 2015.1.429, the Kendo test steps don't work as expected.

For example, when running a recorded step 'KendoInput: Combo open' on a control, the listbox drops down as I expect, but no longer contains any items.  Therefore, when the subsequent step 'KendoListBox: select item by text ...' runs, it cannot find the item, and the test log shows the following error:

Item with text ... is not available to select.
InnerException:
System.ArgumentException: Item with text ADM - Administration is not available to select.
   at Telerik.TestingFramework.Controls.KendoUI.KendoListBox.SelectItem(String text)
   at Telerik.TestStudio.Translators.KendoUI.ListBox.KendoListBoxSelectItem.Execute(Browser browser)
   at ArtOfTest.WebAii.Design.Extensibility.HtmlActionDescriptor.Execute(IAutomationHost autoHost)
   at ArtOfTest.WebAii.Design.Execution.ExecutionEngine.ExecuteStep(Int32 order)

This issue has broken almost all of the automated tests in our project.  If anyone has any information on the issue or what I can do to resolve it, I would greatly appreciate it.
