The cable can't be to spec because Type-C extension cables are, by definition, in violation of the spec. It's not a CC problem. The problem is that Type-C has two sets of USB2.0 pins but only one set is supposed to be connected across the cable.

The devices at either end of the cable detect which way each connector is, and connect to the right two pins (or connect them all together for lazy dumb devices). There is no such thing as a female connector mounted on a cable in the Type-C spec. This use case is not supported.

So what happens is you have two cables with USB2.0 on the opposite set of pins across the middle connection and it doesn't work. To make this work the Type-C extension would need *two* internal sets of USB2.0 wires, but of course nobody makes such raw cable.
