Hi,
And what are the categories of the main product of the "DS00104_粉红色".
Why do you not have a default variant for that product ?
How your categories are configured ?
Did you try to just use one category in the "user point" plugin so, instead of selecting a lot of categories you can choose if the product will give points or not by placing the product in a specific (and hidden) category.
