Purchase order printed line twice

[JMMPW]

The Purchase order form that I use is pretty standard, where it shows supplier code and my own code.

I am now facing an issue where I have setup 2 x alternative supplier against the same supplier but different supplier item code.

I have selected one supplier code, and when printing the purchase order 2 lines appeared 

I looks like the second line is a duplicate.  Need some help with fixing the form.

I found my solution.  Realised that the Parent Data Pipeline box was not ticked.
