Fileting a Welded Corner, unsupressing flat pattern breaks filet?

Hello,

     I've got a sheet metal part that I used closed corner, and welded corner, and then filet the welded corner. This worked great, however when I unsupress the flat pattern the filet breaks. Is this normal? Do I have an option set wrong? Is there another way to do this? I don't have to do a welded corner, but couldn't figure out how to get a continuous filet across the closed corner.

Thanks,

Larry
