I'm using TeamCity 9.0.2. I have one project with many configurations. Up until now, it's always seemed to order my build configurations alphabetically. Then I accidentally clicked on the x on the right and hid one of my configurations. When I unhid it, that configuration now displays at the very bottom. I would like to move it back where it was.
On the right side of the header for each Project, there is a dropdown which has an option for reordering build configurations.
