"Loft failed, don't know why"

Hi there,
I need to create some “frames” in order to complete my pattern. To do so I thought it would be easy to create lofts between 2 sets of curves.
I found out that if I take just one set the loft works, but if I try to give all the rectangles as the input to the loft it just displays this error: “loft failed, don’t know why”.
Am I missing something? It just seems so easy but I could work my way around this problem.
Thank you for your time.
