Woocommerce product add-ons fields not showing after order completion

I am using Woocommerce and woocommerce addons plugin. When i try to complete an order everything appears normal. When i am at the final step of the order though, the table with products and addons shows there is an addon but not the name of it, so my client can not see the extra materials in an order (only that they exist and how much they cost). Can anyone help me with this?

Thank you in advance!
