conflict with Pinterest for woocommerce pluggin

There is a conflict with the Pinterest for Woocommerce Pluggin.
It is impossible to purchase a variable product : an error message appears, asking you to select the chosen option (digital or physical product) when the option is already selected.
(I can’t link the page because I had to deactivate the pluggin so that my customers can place orders on my site).

Thank you for your help.
