component families

[Krsqk]

Make sure of two things: 1) All the components have the same component family number; 2) The Roman numeral increases for each component (the Roman Numeral data line, not the number in the component name). If that doesn't do it, you could post the first 4 or 5 levels here and let us look at it.

Data roman numerals are just for display purpose.
They can go back like with engines or high-energy weapons and not match the comp name like multiplex tracking.
