What causes this issue?

The mandate is not valid on the due date calculated for the SDD payment
order to be created for collecting the term agreement amount.

collection date + lead days . It derives the lead days and calendar from
the mandate specified in the SEPA Customizing.
The due date can either be the term start date or any date between the
term start date and the latest term start date.
When it generates the payment order for collection, the system
calculates the due date as the current posting date + lead days.
