'Load data' error in Osprey

I’m following the Osprey tutorial, and after selecting the job file and clicking “Load Data,” I get the following error message. Is there any way to resolve this issue?

Error Message:
“tabs” is not a recognized field name.

Error in: osp_onLoad (line 30)

set(gui.layout.tabs, 'SelectionChangedFcn', '');
    ^^^^^^^^^^^^^^^

An error occurred while executing the UIControl Callback.
