Tableau workbook bug fix

I need a tableau expert who can fix a bug on our dispatch targets workbook for me.

In summary. Any order that is received should be dispatched the same day. The driving fields for this are 'date created' and 'adj client due date'. Which ever is later.

There are some complications to this however. The date and time created may be after the deadline. In which case the deadline should automatically move to the next day for that order. This doesnt always seem to be working correctly. So there are some passes that should be fails.
Also there are some orders which arent being picked until after the deadline but are still showing as 'passed'.

Deadlines are:
Delivery Type - Deadline
DPD 10:30 Same day - 3pm
DPD 12:00 Same day - 3pm
MAIL - 3pm
DPD Saturday Same day - 3pm
DPD Saturday 12:00 Same day - 3pm
DPD Two Day Same day - 3pm
TP Same day - 11am

Weekends have been excluded from the calculations
out of hours (before 7am and after 5pm) have also been excluded.

Can send tableau report on request.
