"disable overlay" in customization

Why is it that if I go into “customization / header area / header image” I am sometimes able to uncheck “disable overlay” but sometimes the box will NOT uncheck. I haven’t figured out what it is that I change that allows or disallows this.

Thanks!
James

Dear James,

Thank you for reporting. I can’t reproduce the issue on my test site. Could you confirm if your customizer page is JS error free? You can check it using the browser’s console. Please refer here https://developer.chrome.com/devtools/docs/console

Let me know how it goes.
