How to set due date automatically for each item under checklist based on the start date?

How to set due date automatically for each item under checklist based on the start date? Currently, I set the rule like this (refer below), but the due date is following the date I set the start date instead of following the start date itself. For example, I set the start date as 5/6/2023 on 20/6/2023, but the due date is calculated 10 working days from 20/6/2023. Do you get what I mean?

Trigger:

when a start date is set on a card in list

set the item due in 10 working days
