Button positioning

Need some help with the button positioning. I've got three custom units all based of the Paladin. When I play the map, I can only buy two of the units, since the third one is pushed off screen. I have tried changing Button Position X & Y, but it don't seem to help. Anyone know what to do?

Oh, and I am pretty sure it is not because I have used "bad" positions, I have tried (0,0), (1,1) and (2,2). Maybe it is a bug?

Okey, I know thois probably won't be appreciated by the moderators, but here I go anyway:
Please, help me!

The position of the button is as follow
0123 --> X Pos
abcd 0 --> Y Pos
efgh 1 --> Y Pos
i j k l 2 --> Y Pos


Pos X | Y
A= 0,0
B= 1,0
C= 2,0
D= 3,0

E= 0,1
F= 1,1
G= 2,1
H= 3,1

I= 0,2
J= 1,2
K= 2,2
L= 3,2
