Captivate 2019 11.5.1.499

I am on a Mac using the Fluid Boxes, Responsive Project, with the latest update installed. In Quiz Preferences I want to change the preference for the Quiz to be 'Quiz is Passed' in order to recieve credit, when I press the OK button to save the preferences I get the rainbow spinning wheel of death and have to Force Quit the application.

Does anyone know if this is a known issue and if there is a work around?

Thanks,

Max
