Help for Aimeos

Hello!
One issue with ordering.
At the end of ordering process I get this error:
Invalid time interval format "P0Y0M4W0D0H"
Please, for help!
Best regards,
Goran

// Typo3 10.4.11 / Aimeos 20.10.4 / PHP 7.3 / Linux //

Do you have a stack trace of the error?

Right now I fix it
But now ... another problem!
When somebody buy one product and pay it (PrePay - Bank transfer), system it's not put him in user group!
In attachment is prtscr of product configuration!
Best regards,
Goran

Does it work for other payment options?

I don't know. I have tested only with PrePay!
In any case, I must to integrate Stripe more. Only this two payments will be active!
