discount summary is wrong with volume based discount

[daleto]

Discount for shoppers are positive value
But calculated as negative which is correct
Volume based discount are negative number and calculate correctly per product

But the total discount will be summarised wrong

See attachment as an example

How to fix this

Apart from that the discount summary is wrong the strike through does not work when the pdf gets created.
Which can be misleading for customers
