NX Position of views on the drawing sheet shift after view update

When we open the drawing all views are out of date. When the drawing is updated all central views, aligned vertically with one another, moves to the left. 
Why does this happen?

Solution

When a drawing view is created in drafting the standard view boundary type is Automatic Rectangle. When such a view is created NX automatically gives the view an Anchor Point. The anchor point chosen is the point in the drawing view closest to the center of the view. A typical point chosen would be the center point of a hole.
You can see and edit this Anchor Point by selecting the view - right mouse button -> Boundary
There is an Anchor Point button in the View Boundary menu
That can be used to re-locate the Anchor Point.
 
What happened in this particular case was that the position of the hole, upon the creation of the drawing view chosen for anchor point by NX, have been moved in the model part file relative the left edge of the model. So when the hole is moved in the model it gives the impression that the view on the drawing is moved as the hole maintains it position on the drawing.
