Hi,

I need urgent help please.

 I am on Magento 2.1.7

Problem 1: the catalog price is set for example €89  but in the front end, the item shows €71.77. 

what am I doing wrong?

Problem 2:   I am using PayPal as payment gateway. At the shopping cart, the tax is calculated wrongly and the final total amount is all wrong.

The same applies to any discount applied.

here are my configuration settings for tax calculations and PayPal payments:
