Help With Unique District

[Seamus19]

I am creating a unique civilization with a unique district that replaces the campus. So far I have added the new district, called the academy, into the game, but when I look at the available districts to construct the campus is still in the list as well as the academy

After I build the Academy the campus is not available to build and I guess that is something. But another thing is that I would like the Campus buildings to be built in the academy but they are not available.

Attached is the Academy xml file. If you need anymore files please ask.

UPDATE: I have solved the problem by adding

TraitType="TRAIT_CIVILIZATION_DISTRICT_ACADEMY"

to this line of code and now all my problems are solved

<Row DistrictType="DISTRICT_ACADEMY" Name="LOC_DISTRICT_ACADEMY_NAME" Description="LOC_DISTRICT_ACADEMY_DESCRIPTION" PrereqTech="TECH_WRITING" PlunderType="PLUNDER_SCIENCE" PlunderAmount="25" AdvisorType="ADVISOR_TECHNOLOGY" Cost="50" CostProgressionModel="COST_PROGRESSION_NUM_UNDER_AVG_PLUS_TECH" CostProgressionParam1="40" Maintenance="1" RequiresPlacement="true" RequiresPopulation="true" Aqueduct="false" NoAdjacentCity="false" InternalOnly="false" ZOC="false" CaptureRemovesBuildings="false" CaptureRemovesCityDefenses="false" MilitaryDomain="NO_DOMAIN" CityStrengthModifier="2" TraitType="TRAIT_CIVILIZATION_DISTRICT_ACADEMY"/>
