Adamantium and ECM refuse to use defined prerequisites.
Please help me out here, I'm at wits end.

I've defined Duralthene as the requirement for Adamantium Armor, yet as it shows above it seems permanently attached to Superior Tri-Stronium
with ECM it is glued to Missile Defense Theory when I've defined Smart Chaff as the requirement.
Please help me out here, I'm at wits end.
