Yeah that's exactly what happened. I ran out of your cables and I sent your design to a cable company to have them made.. I haven't had time to even look at it yet but Occam's razor says they didn't follow your instructions correctly. We already had that problem with the small adapter I had to have them remake that. I'll dig into it and see what I can find out.
