"Select Configuration" Where is it driven from

I have a Fastener...3/8 size has 19 avail lengths driven by design table. however when i insert into an assembly the 3/8 size shows 22 sizes avail.  if i use any of the 3 "extra" sizes SolidWorks crashes.

Where is the below table driven from?

My question is where is this driven from.

I checked in the design table & configuration publisher...Nope, not in there.

I checked in the "Smart Feature" in context of assembly....Not there either.
