left and top edges are positioning relative to the screen, right and bottom edges are scaling relative to the screen.
and If I read correctly (could only explore the capx with a zip and text editor), you are setting right and bottom edges on some of them.
setting left edge to left will position it relative to the left border of the screen (the left border and left edge will be at the same distance)
setting left edge to right will position it relative to the right border of the screen
setting right edge to right will make it stretch to have its right edge at the same relative position to the right border of the screen without touching the left edge
same logic for top and bottom
that is why on your screenshot some are placed as intented at the top, continue only using the left and top edge on the bottoms one to have the same result.
