Report: scaling a part smaller may not affect launch collision bounds correctly

[KSAMissionCtrl]

Here is the setup in the VAB:

The part is from the B9 Aerospace Pack. Here is the result on the pad:

When I create my own scaled part everything works fine:

Here is the config I am using for my scaled part and my attempts to modify the original part to fix the behavior:

+PART[B9_Structure_HX2_U]
{
    @name = B9_Structure_HX2_U_KSA
    @rescaleFactor = 0.27
    @title = HX2-U Universal Module for MLP
    @mass = 2.5
    @node_stack_top0    =  0,     4, 0,      0,  1,  0, 4
    @node_stack_top1    =  3.41,  4, 0,      0,  1,  0, 2
    @node_stack_top2    = -3.41,  4, 0,      0,  1,  0, 2
    @node_stack_bottom0 =  0,    -4, 0,      0, -1,  0, 4
    @node_stack_bottom1 =  3.41, -4, 0,      0, -1,  0, 2
    @node_stack_bottom2 = -3.41, -4, 0,      0, -1,  0, 2
