Deleting points from a list of points breaks the output in 8.0007

New to 8.0007 I find if I manually delete a point from a set of points that are loaded into a point parameter object the final geometry does not regenerate.  I have to manually reload the points every time I delete one.  In a side by side with version 8.0004 you'll see the older version works fine.  Dragging points works fine.  Also, this attachment requires weaverbird and i'm using Rhino 5.
