Probably your custom TC is broken.  I would guess that it is either
dropping the Delay_Req or mangling it beyond recognition.

You can confirm the non-zero correction field is NOT the problem by:

1. setting delayAsymmetry to 1
2. take your buggy TC out of the loop (use 2 PCs point to point)
3. observe how it works just fine

Thanks,
