ship modding : multiple weapons pb

[trooper]

I don't understand the way weapons are chosen in ships....

in designCreation.txt file, what is the meaning of :
Majority Weapon Family Pick 1,2,3...
and
Secondary Weapon Family Pick 1,2,3...

I wanted to have both missile and beam weapons on my ships, so I tried :

Majority Weapon Family Pick 1 := 25 (uranium depleted cannon)
Majority Weapon Family Pick 2 := 3 (meson bLaster)
Majority Weapon Family Pick 3 := 0
Majority Weapon Family Pick 4 := 0
Majority Weapon Family Pick 5 := 0
Secondary Weapon Family Pick 1 := 2 (capital ship missile)
Secondary Weapon Family Pick 2 := 4 (anti-matter torpedo)
Secondary Weapon Family Pick 3:= 0
Secondary Weapon Family Pick 4 := 0
Secondary Weapon Family Pick 5 := 0

but it seems that only majority weapon 1 is added on the ship. a solution ?
