Can't create individual shipping calculation

Hello,

I’m refering to documentation page on:

https://docs.shopware.com/en/shopware-5-en/shipping-costs-and-payment-methods/individual-shipping-costs

I’m trying to get Calculations field in Advanced Configuration to work where i would place my query to calculate the shipping costs. However my shipping cost gets selected from Shipping costs tab. I have set Calculate dispatch cossts based on to Calculation but it still doesn’t seem to work.

I’ve tried to place 1 and TRUE in Terms but it doesn’t seem to change anything.

In this example i expect my shipping costs to be 85€ but they’re 50€.
What am I doing wrong?
