If you attach your part, it'll be easier for us to investigate.

Hi! I guess the two flanges overlap and they are merged together. In that case, Corner Seam will not allow the edges to be selected. Please edit the each flange and expand the dialog -> change extent option to Width or Offset. So that the two flanges don't merged. After that, Corner Seam will work.

Many thanks!
