"1 week" in OmniPlan means 1 work week, not 1 calendar week. This is the same reason why a task that takes "1 day" means it takes 8 working hours from 8AM to 5PM, not 24 hours.

If you want 1 week to mean 7 days, you have to change the hours per week in the Project : Formatting inspector from 40 hours to 56 hours.
