Showing Bend Lines

To start with I'm new to Solidworks 2014 but have used previous editions. I have created a few sheet metal parts and am having a hard time getting the bend lines and annotation to stay in the drawings. I can get them in, but the next time I open/update the drawing or part they disappear and I can't get them back. How do I get them to stay?

Regards,

Kevin
