Extruded Cuts going weird when flattening the sheet metal.

Hello, I have a problem that I have created a part and there are a couple of angles in it (but nothing too complex). I have made extruded cuts on these angles, once they have been flattened. When I bend them again, they are fine and look all correct, but when I go to flatten the part, the lines get all messed up!!!! Help please.

Part is attached.
