Min products set to 0

Hi, I try to config your plugin like this example:
https://demo.wpclever.net/woosb/product/smart-bundle-02/

I config:
Preselect options: 2 productos with 1 item set the rest to 0 items.
Personalized quantity: set to YES
Limit of each products min 0, max 2
Limit of all products min 2 max 2

And when i preview the bundle product all the products are preselected to 1 item per product and i can change it to 0.

Can you help me with it?
