While preparing for the next upgrade of Confluence, I noticed that the "General Configuration" Navigation menu is difficult to use because the emphasisis of headlines and the separators are gone. Not sure which version introduced this problem, may be any between 6.7 and 6.9.

I suspect that the so called "fresh, new look" has created this weakness as a side effect.

Please verify your stylesheet and bring back the earlier appearance.

See the attached screenshots of 6.5 and 6.9 for illustration.
