looks like incorrect yaml formatting for a list:

classes:
    gladiator:
        displayName: "&4Gladiator" ### Used for signs
        items:
        - iron_sword: 1
        - bow: 1
        - arrow: 16
        - iron_helm: 1
        - iron_chest: 1
        - iron_leggings: 1
        - iron_boots: 1
        - fishing_rod: 1
