woocommerce gravity forms product addons not sent

Hi,

I sell products and in some cases I use woocommerce gravity forms addons to add certain product addons to the products. when the users use the quick checkout button the chosen addons arent saved.
Do you have any idea what might be causing this & how to resolve it?
I’m using the github version of last week.
thanks a lot and have a nice weekend
