VM 2.0.14 ordering generic child variants during import

[spyderwebdesign]

In the past, generic child variants were displayed in the product drop down menu in the order that they were added into VM. I have all my size 5 add first, then size 6, then size 7, then size 8, etc...

In VM 2.014 when I import in order (5,6,7,8,9,10,11,12); my sizes are all out of order in the drop down list. It currently shows Size 6, Size 8, Size 10, Size 5, Size 7, Size 9, Size 11.

Does anyone know the new rule of how generic child variants are listed so that I can reorder my child products when I import? I have 18,000 products and do not want to have to manually order all the children
