That's easy:
Find the line containing "PointSpentInTree" and delete it.
Find
DataSource="TabSource" and change it to
DataSource="TabSource2".
Find </DataSource> and insert this after that line:
<DataSource Name="TabSource2">
<Data Name="Traits" Target="Traits" text=":6936cd407cc9c0f3:Character Development" />
<Data Name="Shadows" target="Exp05" text="Shadows" />
</DataSource>
