Good to hear from you. Tim's on holiday for a week, but i think i can help you.
If you look at the attached PM6 IEC manual, (page 75+page 76) for the 2006 limits.
section(3) of the standard implementation states ;
"3. Harmonic currents less than 0.6% of the input current or less than 5mA, whichever is greater, are disregarded"
As you can see on your pictures, all the "N/A" labeled ones are below 5mA,
So the standard itself asks to not consider them.
We labeled these as "N/A" rather than "Pass" to be more precise; the standard does not set limits for <5mA readings.
I hope this helps
