lead time Rollup is incorrect

Summary:

We are in process manufacturing.

When we run "Calculate Lead Times and Roll Up Cumulative Lead Time", The 'Processing lead time (Processing Days) ' populated on the item (PIM) is 1.4222

However, when we create a work Order for this item the start and end date are populated as :

Start Date - 01/04/25 02:51 PM - Completion Date - 03/04/25 12:51 PM

This difference between start date and completion date on the Work order does not match with the Processing Lead time on Item attributes

The Batch size on the work order and Lead time lot size on item attribute is same.
