Signal direction of RCA from AQ are wrong or I'm wrong

Hi there

I bought 1set(R,L) of 2meter RCA cable. I want to split them to 2 sets (1meter each) so I cut them in half and to expect to see 2 wires and a shield. Instead I found 3 wires and a shield. That would be no problem to reconnect to new RCA jack just to use multi-meter to test how they are wired for each. But what I found is strange, each cable (R and L) are difference wired.

In the photo there are yellow, white, blue and shield. Same direction arrows but the White arrow jack: all white, blue wire and shield are connected to jack ground.

While the Black arrow jack: only white wire is connected to jack ground. 😕

For this side of arrow, both cable had same wired: white and blue are connected to jacks ground (no shield connect)

Is this factory or something?😕

If mistake by factory, any one know how to correct them or how to connect for each direction? For 3 wires and a shield?

(For 2 wires and a shield: one wire should combine to shield at one end and separate at the other end. )
