Tax double addition

Hello, I am using Woocommerce 3.0.2 and found that although i have these options selected :

1.prices entered with tax :Yes, I will enter prices inclusive of tax
2.display prices in shop/cart/checkout : including tax

woo keeps adding tax again.

my website url is https://www.keepitpure.gr

example this products costs 25euros tax included. However tax is added again.

My other site with the exact same settings does great.

Thank you for your kind attention.
