incorrect quantity of customized products

[ilario]

HI

I have a problem with the quantity of products with customization,
I practically double the quantity but only in the BO
in the cart and in the customer order (front) it is correct, in the cart and order BO is doubled, he takes the quantity from the "ps_customization" table and I notice that it has been saved doubled not 35 but 70

Can you please tell me in which file it is saved, so as to check why it doubles it

I attach an example of the shopping cart in BO

thanks

Ilario
