Product addons doesn’t appear on checkout/order.

Hi,
We used booster for many years, and everythings worked fine.

We use product addons to display and add fees to a product.

We use only radio button.
On the product radio button works, price changes and everything is working. But when the customer add it to the cart, and checkout, the order is appear without all the option.. And so we have so much order whitout any options.

We didn’t change anything since many years, and now it’s not working.

Sometimes it works, sometimes no.
A client made two order, exactly with the same option and same product.
First : KO
Second : OK. (We had all the options on the order..)

Thanks in advance,
ND
