Blocks - Spot the difference!

This has now become an issue amongst our department....

We have a library of schematic blocks in our library. When created they clearly show the line styles (chain, phantom, solid etc). However, when we 'drag and drop' the required schematic block into a drawing, the line styles are view as solid. When we go to edit the block within the drawing, all the line styles default back to how they were originally created. See attached screen shots to understand our problem.

Thanks in advance...Brian
