Overlapping weight-based shipping rules don't get added together

[Beluga]

I have rules like this, in this order:

0 kg - 1 kg = 0.18 €

0 kg - 10000 kg = 8.8 €

1 kg - 2 kg = 0.18 €

2 kg - 3 kg = 0.18 €

and this continues to like 200 kgs.

 

If I order a 250g product, the shipping before taxes should be 8.98 €. Instead, it is only 0.18.

For a case of a pack consisting of 4 x 250g products, the shipping is 8.8 €, so it doesn't add the two 0.18 euro costs.

For an order totaling 40 kg, the shipping was also 8.8 €.

 

If the system works differently than I have presumed, one solution would of course be to use absolute costs for every 1 kg weight range rule.
