I just got off the phone with Worksman, and the rep. seemed as confused as I am. I just emailed them a couple of photos of the hinge, which I think that they will be able to see the problem and offer a solution. BTW, she confirmed the the Walmart Tri-Fecta and the Port-O-Trike are exactly the same trikes. When I suggested that their website misrepresents the trike, she balked, saying there was no impropriety. Personally, I expect to get exactly what I paid for, especially when I paid more than I had to. Don't know how this is going to work out yet, will just have to wait and see.
