Sorry, but I really don't understand what the problem is.
Could you please try to explain it better, and also provide some screenshot (image/images) displaying the problem?

Sorry, those tells me nothing. I only see two different orders, taken from your database, nothing wrong with that in my eyes.
You have to explain your problem properly.

NO! Request 21 024 is nonexistent! Client did request and True 21025. Any application lodged with duplicate:1 - on Bank 2 - real customer

I don't understand you, sorry!
Would it be possible for you to get someone to help you writing this more in details, in English?

PS! Note the status filter for 'Missing Orders', the temporary saved orders not being completed, who is compleately normal: https://arastta.org/docs/user-manual/sales/orders

I think he is saying a customer made one transaction.
the correct transaction is 21025.
But when the transactions are made, it creates 2 table entries. 21024 and 21025.
The first is a duplicate of the second.

Maybe, but then I would expect a screenshot from the store admin, not the database.
Also, they are not duplicates as they are different. Most likely he's just digging in a place he shouldn't be, and don't understand, looking himself blind at 'Missing Orders' - those being temporary stored.

YES! This is exactly!

Is it? Please provide a screenshot from your Arastta stores order list in admin, displaying the duplicates.
They are not duplicates anyway, since they have different info stored.

PS! Did you care to look at the info and links above, to better understand the system?
