Number 1 and 3 are abillities of Gil-Galad.
Number 2,4,5 and 6 are all posible.
But because the spell is nearly the same for Imladris and Arnor, I believe it is 6 and the other ones are older versions.
So just change Nr. 6 to this. Just set the count of the Gil-Galads for Bruchtal to 0:
CreateObject
ObjectNames = ArnorGilGalad_Summoned
Count = 1
FadeIn = Yes
FadeTime = 8000
IgnoreCommandPointLimit = Yes
Disposition = ABSOLUTE_ANGLE
DispositionAngle = 270
UseJustBuiltFlag = Yes
StartingBusyTime = 5000
Offset = X:-30 Y:-60 Z:0
ForbiddenUpgrades = Upgrade_ImladrisFaction
RequiredUpgrades = Upgrade_ArnorFaction
End
CreateObject
ObjectNames = BruchtalGilGalad_Summone d
Count = 0
FadeIn = Yes
FadeTime = 8000
IgnoreCommandPointLimit = Yes
Disposition = ABSOLUTE_ANGLE
DispositionAngle = 270
UseJustBuiltFlag = Yes
StartingBusyTime = 5000
Offset = X:-30 Y:-60 Z:0
ForbiddenUpgrades = Upgrade_ArnorFaction
RequiredUpgrades = Upgrade_ImladrisFaction
End
It would be also possible to delete the whole part for Imladris, but if you want to rechange it, it is better have the old codes still there.
