xoo_wsc_add_to_cart from the sidecart woocommerce creates and extra cart entry

Hello, i am having an issue with making a plugin that hooks to the woocommerce plugin. Currently my issue is with the xoo_wsc_add_to_cart, that adds an empty entry to my cart as an extra entry (see picture).
is it possible to stop the sidecart plugin from doing this? in advance, Thank you!
