Auto Relief

When I try to add Edge-Flange to sheet metal SW 2008 won'tadd relief automatically although this option is enabled with ratio0.5. I have to edit sketch of the flange, make it shorter so itdoesn't connect to radius of the bend to have the relief created. Iremember in was done automatically in previous versions. Is my SW2008 not working properly? If so , how to fix it?

Thanks for help
