是否将自定义列添加到TFS中的UI?

这是因为您在步骤3中在旧表单/团队资源管理器下添加了控件。如果返回到旧表单,您将看到此字段。为了使控件以新的web表单显示,您需要将控件添加到 <FORM><WebLayout>...</WebLayout></FORM> :

  <FORM>
      <WebLayout>
        <Page Label="Details" LayoutMode="FirstColumnWide">
          <Section>
            <Group Label="Details">
              <Control Label="Priority" Type="FieldControl" FieldName="Microsoft.VSTS.Common.Priority" />
              <Control Label="Effort" Type="FieldControl" FieldName="Microsoft.VSTS.Scheduling.Effort" />
              <Control Label="Business Value" Type="FieldControl" FieldName="Microsoft.VSTS.Common.BusinessValue" />
              <Control Label="Time Criticality" Type="FieldControl" FieldName="Microsoft.VSTS.Common.TimeCriticality" />
              <Control Label="Value area" Type="FieldControl" FieldName="Microsoft.VSTS.Common.ValueArea" />
              <Control Label="AHA Reference" Type="FieldControl" FieldName="AHAReference.AHAReference" /> 
            </Group>
          </Section>
        </Page>
      </WebLayout>
    </FORM>
