Annotation Problem

Hi,
it's me again^^ I have a problem with Annotations.
I need 4 annotations for my plot, 2 RectangleAnnotations and 2 Arrowannotations. The Arrow Annotations working fine, but the rectangle Annotation is somehow weird.
You can look at the problem on the screenshot i provided.

Here is my code for the Rectangle Annotations:

var recAnnotation1 = new RectangleAnnotation();
            recAnnotation1.MinimumX = 0;
            recAnnotation1.MinimumY = 0;
            recAnnotation1.MaximumY = listItem[listItem.Count - 1].WealthList;
            recAnnotation1.Fill = OxyColor.FromArgb(99, 255, 0, 0); ;

            var recAnnotation2 = new RectangleAnnotation();
            recAnnotation1.MinimumY = 0;
            recAnnotation2.MinimumX = 0;
            listItem.Sort(delegate(ListCarrier l1, ListCarrier l2) { return l1.WealthList.CompareTo(l2.WealthList); });
            recAnnotation2.MaximumY = listItem[listItem.Count - 1].WealthList;
            recAnnotation2.Fill = OxyColor.FromArgb(99, 0, 128, 0);

            temp.Series.Add(ls);
            temp.Annotations.Add(recAnnotation2);
            temp.Annotations.Add(recAnnotation1);
