When modding any AbilityBonusOption, it is a very bad idea to include everything in the mod file. This will lead to every modifier being counted twice - if you have a trait that gives +2 strength, it will give +4 instead. This also applies to ImprovementTypes (buildings), but mostly not to other types like items and units.
This is an example of a mod file that makes Wealthy add 500 gildar. Nothing else is needeed in the file.
<AbilityBonus InternalName="WealthyAbility">
<AbilityBonusType>Champion_Talent</AbilityBonusType>
<AbilityBonusOption InternalName="Wealthy">
<DisplayName>Wealthy</DisplayName>
<Description>Sovereign starts with an additional 500 Gildar</Description>

<AIData AIPersonality="AI_General">

</AIData>
</AbilityBonusOption>
</AbilityBonus>
You'll see it is only +350 here, as we already have +150 from the installation file.
