It has to do something to improper association of lines and points for the different blocks made.

Yes, some of your associations are wrong. You can either delete all of them edge/node associations and reassociate or fix them one by one.
To visually see the associations, in the left treeview go to edges -> right mouse button -> show associations. This will add arrows to edges and show you where ICEM tries to fit the block edges to the geometry lines. Sometimes one wrong association screws up the whole mesh.
