Range of my custom unit

I am trying to edit the rifleman to a custom unit (a long range siege mech).

I've given him siege attack, a new projectile, a projectile arc, new collision size, new scaling size, selection circle, new damage, cooldown, etc. etc. etc.
But the range is stuck at 600. I am not sure why I can't put it to my value (1200). Any help would be apprieciated...

It says whatever value in the editor, but whenever i go to test the map out, the range is still 600 :(

I use WE Unlimited

EDIT:

It seems as if all my units (Mortar included) cannot have their range changed.
Can anyone help me?

Do not forget to also modify the acquisition range.

Idiocy (or noobness i should say) has been overcome :)
thanks mate
