When I try to add Edge-Flange to sheet metal SW 2008 won't add relief automatically although this option is enabled with ratio 0.5. I have to edit sketch of the flange, make it shorter so it doesn't connect to radius of the bend to have the relief created. I remember in was done automatically in previous versions. Is my SW 2008 not working properly? If so , how to fix it?

Thanks for help
