If I enter the following secondary links (from top to bottom) through administer>>global settings, Civicspace returns them in the reverse order:

Entered (from top to bottom):

About Us
Get involved
Contact Us
Feedback

Returned (from left to right):
Feedback
Contact Us
Get involved
About Us

Occasionally, I have also noticed this order being broken. For example, 'Get involved' appearing after 'Feedback' from left to right.
