discount amount on checkout page

[web-itc]

Hi

On www.web-ict.be we want to add some discount.  All works fine.
However the "problem" we have is that when you are on the checkout page, the price mentioned is the price with the discount already deducted, with the VAT amount.  If you are adding these 2 together you come to the same (=correct) amount to pay.
But the discount mentioned is a bit confusing.  How can I make this discount amount and text dissapear without making them dissapear on the product page and the product detail page?

Thx in advance

Anyone?

I am using all latest versions as well of Joomla (3.8 ) and Virtuemart 3.2.  For php I use 7.0
