No Constraint Options for Device, Browser, Platform

I am trying to analyze email opens by device, platform, and browser but I do not get any options in the dropdown when pulling email performance reports. I tried using Email Insights but the only options available are for device type (windows, desktop, or other). How do I add values for these constraints? Is there any tracking code I can add to my emails?

Any info would be helpful!

Thanks
