Sketchup Preferences 2015 for mac missing items?

It seems that Sketchup 2015 preferences is missing a “Files” heading and a “Compatibility” heading. Is this true or is it just me? Have they been moved by Sketchup? Deleted? I would like to make changes to “Files” but can’t.

Please advise.

Thanks,

Joel
