New Quizzes: "This tool needs to be loaded in a new browser window" upon launch

[ldavenport4015]

We have had multiple instances this semester where students are unable to access a New Quiz. Instructure Support escalates the tickets to engineering, and the reply states, ".... I was able to confirm that this quiz was also set to launch in a new tab. I set this value to false through API so the quiz should launch as expected. "

Can anyone help me check for New Quizzes where this setting is applied? And/or provide any insight into how this happens. I can see that it need to be loaded into a new tab when I click Build, but it does not prevent me from editing the New Quiz. However, students get an error when trying to take the exam. 

Thanks for your help!
