Wondering if this is normal

Drawing a medium complex tubing frame structure of 1.5" x 1.5" x .083 wall steel.

the bottom, 2 sides and, 2 ends of the structure are normal to the top, front, and right planes. But the 2 front corners have a diagonal structure connecting the sides and ends. The tubing sides in these corners are supposed to be perpendicular to the top plane. But the tubing created in these diagonal corners won't stay perpendicular to the top plane, it's off like 2 degrees. Double checked the sketch and it's all perpendicular.

In the pic the highlighted faces are the ones that aren't perp. the compete top rail was created with one "structural member". You can see the center front were the top rail is mirrored, there's a kink in the middle of the tube because the faces are off 2 degrees.
