Seems the OP did not assemble the benchwork according to the instructions. The I-beams meant for the top were not installed and instead put on the bottom. That’s why it seems that he had some extras.
Not sure if this weakens the structure or not.
Hmm... layout seems flat and stable to me. Thanks for checking though!
