[Help!] Cannot assign the units in custom map to the player

[Guest Grishnakh]

I customize a map and put some unit on it.

following are what I put

A nuclear missle launcher (NML)

A Particle cannon (PC)

2 Emperor tanks

2 paladin tanks

4 powerplants

and all are set to skirmish american laser general

...but when I choose laser general as player in skirmish mode

only a NML and a PC are belonged to me....

 

whats wrong with my setting?
