PTN5150A DFP Mode

I am trying to make a USB3.0 Redriver using two PTN5150A and PTN36043A each.

I have added a block diagram on top of the attached schematic.

CC Controller does not operate normally in CONN2 of the block diagram.

I can only use Low=CC2 mode in External selection.

Is my schematic wrong?
Does NXP have a suitable redriver solution for Type-C?

Could you please re- attach your schematic file? I can't open it!

My Redriver aims to support a Type-C connector capable of bi-directional flipping of both input and output using two PTN5150A and two PTN36043A.
Can I just set the DFP and UFP by controlling the PORT pin high and low?

If not, what setting should I do via I2C?
My Redriver connects like this:

PC --- Type-C --- Cable --- Type-C(flip1) --- PTN5150A --- PTN36043A --- PTN36043A --- PTN5150A --- Type-C(flip2) --- Cable --- Type-C --- Device
