Label design property

Hi guys, this is very stupid question, but in my WD4A application, I have a label where the design is standard,

according to this Link: [http://help.sap.com/saphelp_nw2004s/helpdata/EN/4f/f08841e3af1609e10000000a155106/frameset.htm]

Why I don't have the vertical bar at the left of the label?

Or what I have to do to get this vertical pipe on the left?

thanks

Alex
