Prices of Multiple values getting picked in order (Variant Configuration)

Hi Gurus,

i have a VC done for a box as per below structure

BOX

Thickness (characterstics - Multiple Values Allowed)

Thin

Medium

Exrta

Packaging (characterstics - Multiple Values Allowed)

Plastic

Bubble

layered

Now in Sales order for the Box, even though I am selecting the values of Thin thickness with bubble packing, it is still picking the values of medium, extra and plastic and layered values.

I am using SAP standard condition VA00 and the condition is statistical.

Please suggest some pointers.
