Describe the bug
when i define 2 parameters for the customizer

ScalarRange1= 12; //[1:2:50]
VectorRange1=[12]; //[1:2:50]

which gives me this

notice that the scalar value is 13 and the vector item is at 12.
They should be the same, no?

i suspect the scalar value being 13 is due to the increment of 2 and the minimum of 1 adjusting to a valid value for the param.

i also notice that decrementing the scalar to the minimum, 1, and the incrementing it now jumps along the odd numbers, and that cant be right.

i have seen a few other oddities in the way customizer handles mismatch between default values and specifications but this, to me, is clearly a bug.
