            <se:DisplacementY>-25</se:DisplacementY>
        </se:Displacement>
        </se:AnchorPoint> 
      </se:PointPlacement>
    </se:LabelPlacement>
    <se:Halo>

Answer 1

There may be something else wrong with your style as

       <LabelPlacement>
          <PointPlacement>
            <AnchorPoint>
              <AnchorPointX>0.5</AnchorPointX>
              <AnchorPointY>0.5</AnchorPointY>
            </AnchorPoint>
            <Displacement>
              <DisplacementX>-25</DisplacementX>
              <DisplacementY>-25</DisplacementY>
              </Displacement>
            
          </PointPlacement>
        </LabelPlacement>

works for me:
