Modding an improvement with district adjacency bonus

[Kastor12]

Hello, I found a Mod called Merrick's Palmyra and I wanted to edit the unique improvement. I was trying to make it give a standard adjacency bonus to holy sites, but somehow it does not work. This is the code i edited:

<Improvements>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS"
Name="LOC_IMPROVEMENT_MER_FUNERARY_TOWERS_NAME"
Description="LOC_IMPROVEMENT_MER_FUNERARY_TOWERS_DESCRIPTION"
Icon="ICON_IMPROVEMENT_MER_FUNERARY_TOWERS"
PlunderType="PLUNDER_FAITH"
PlunderAmount="25"
PrereqTech="TECH_MASONRY"
Buildable="true"
BuildInLine="true"
TraitType="TRAIT_CIVILIZATION_IMPROVEMENT_MER_FUNERARY_TOWERS"/>
</Improvements>
<Improvement_ValidTerrains>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" TerrainType="TERRAIN_DESERT"/>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" TerrainType="TERRAIN_DESERT_HILLS"/>
</Improvement_ValidTerrains>
<Improvement_ValidBuildUnits>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" UnitType="UNIT_BUILDER"/>
</Improvement_ValidBuildUnits>
<Improvement_YieldChanges>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" YieldType="YIELD_FAITH" YieldChange="1"/>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" YieldType="YIELD_GOLD" YieldChange="1"/>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" YieldType="YIELD_CULTURE" YieldChange="1"/>
</Improvement_YieldChanges>
<District_Adjacencies>
<Row DistrictType="DISTRICT_HOLY_SITE" YieldChangeId="Funerary_Faith"/>
</District_Adjacencies>
<Adjacency_YieldChanges>
<Row ID="Funerary_Faith" Description="Placeholder" YieldType="YIELD_FAITH" YieldChange="1" TilesRequired="1" AdjacentImprovement="IMPROVEMENT_MER_FUNERARY_TOWERS"/>
</Adjacency_YieldChanges>
<Improvement_Tourism>
<Row ImprovementType="IMPROVEMENT_MER_FUNERARY_TOWERS" TourismSource="TOURISMSOURCE_FAITH" PrereqCivic="CIVIC_CONSERVATION" ScalingFactor="100"/>
</Improvement_Tourism>

I can't see anything wrong in that but when I test it ingame, the improvement does not give any adjacency bonus for the holy site.
I would be glad if anyone could help me out and I'm sorry for any language misstakes.

I don't see any issues right away. Did you check C:\Users\PC\Documents\My Games\Sid Meier's Civilization VI\Logs for any errors?
