tax on Total is only the tax of the Shipping

Using the link with Shipment Manager, Woocommerce shows only (tax/btw) for the shipping value, not the tax on the total order value.

Our woocommerce is defined ‘tax included’. Shipping Manager is also tax included. Why is total then only showing tax of the shipping and how to resolve.

Please reply to my ticket so i can send you screenshots to clarify.

thx,Olivier
