Please fix it.

I'm using latest version of Indesign, Mac MoJave
Same here - CC 2018 and Sierra 10.12.6. Nothing at all happens when I click on any of the arrows/triangles

We would be needing a little more information such as...
1. What happens when you click on the "arrows" before each entry of the pre-flight panel
2. Is this issue specific to one document or is reproducible with all documents you create?
3. Are you using the latest version of InDesign ( CC 2017.1)?
4. Your MAC OS version?
