Incorrect amount in the refund slip

[Cypher-key]

Hi, I encountered a really problematic bug.

On Prestashop 1.7.6.7

When you generate an order slip, there is a tiny amount that make it does not match with the rest of the order.

Here's an example with an order at 4018.26€, but on the refund slip, the amount is 4035.42€.

Please do note that the amount IS correct on the order, on the refund tab (present on the order page), AND in the database. No amount of 4035.42€ or 17.16€ are present anywhere.

The problem seems to come from the total_paid_tax_incl variable from the Order class called on the HTMLTemplateOrderSlip.

Can you help me with that ? Do somebody have encountered the same kind of problems ?

Thank you for your help !
