Financial Project Completion

Hello everyone,
I'd like to thank you for your help with my concern about completing my financial projects.
In fact, when I try to complete my financial project, it tells me that there is an unbalanced voucher (Details In the first screen shoot), which prevents me from finishing the process.
When I look at the voucher number that the message mentions, I can see that my voucher are well balanced and are already in the GL (In second screen shoot).
So, if anyone has already encountered this error, can you tell me how I can resolve it?

Attached is a screenshot of the error message.

Thanks to all
