Thats so weird, did you wind up coloring one end or something? I still wish we would add color to USB C wires like USB 3 has to emphasize features and expected uses. USB C was a much needed change from USB3 and 2 in terms of being reversible and superior but every manufacturer implements the cables differently and its confusing and hard to figure out which cable is best for what.
Some cables write 10Gbps and similar near the end.
