[R&F] Error and not sure why

[Casworon]

I'm making a mod to allow all civilizations to rush the production of wonders by 10% using a builder charge.

I first modified china's ability to remove the free worker charge and change the wonder percentage by 10%

<GameData>


        -<ModifierArguments>

            <Delete ModifierId="TRAIT_ADJUST_BUILDER_CHARGES"/>


            -<Row>

                <ModifierId>TRAIT_ADJUST_BUILDER_CHARGES</ModifierId>

                <Name>Amount</Name>

                <Value>0</Value>

            </Row>

            <Delete ModifierId="TRAIT_BUILDER_WONDER_PERCENT"/>


            -<Row>

                <ModifierId>TRAIT_BUILDER_WONDER_PERCENT</ModifierId>

                <Name>Amount</Name>

                <Value>10</Value>

            </Row>

        </ModifierArguments>
      
</GameData>

Then i changed the max build era so it can rush wonders in any Era

<GameData>
    <UnitCommands>
        -<Update>

            <Where CommandType="UNITCOMMAND_WONDER_PRODUCTION"/>

            <Set MaxEra="8"/>

        </Update>

    </UnitCommands>
</GameData>

Then i added china's 'first emperor' trait to the other leaders. All using the same template, this is the example for Roosevelt below

<GameData>
    <LeaderTraits>

        <Delete LeaderType="LEADER_T_ROOSEVELT"/>

        <Row LeaderType="LEADER_T_ROOSEVELT" TraitType="TRAIT_LEADER_ROOSEVELT_COROLLARY"/>

        <Row LeaderType="LEADER_T_ROOSEVELT" TraitType="FIRST_EMPEROR_TRAIT"/>

    </LeaderTraits>
</GameData>

This worked fine for the original leaders from the vanilla civ vi release and also works fine for the Rise and Fall civs. However when i try this with DLC leaders it creates an error and doesn't work. But i have no idea what i'm doing wrong

Solved it. Just needed to add the DLC's as dependencies
