Start Date field: never after the due date
The date the work starts. It can’t fall after the due date in the same record.
How it works
Every start date in the unit is compared with every due date in the same record.
The same day is allowed.
When you edit, the new values are compared with the saved ones, so you can’t push the start past the existing due date.
The order isn’t checked if either date is empty, or if the field is hidden by conditional visibility.
An old record that breaks the rule can still have its other fields edited.
Regular date fields aren’t tied to this rule.
The update field action in automations doesn’t check the order.

What to do
“Start date: must be on or before the due date”
The start is after the due date.
Correct one of the two dates.
