Duplicate Invoices with the same UUID

Al salamualaikum

Our system by technical bug resend a huge number of the same invoices, and the response for all was ‘Reported’:
UUID is the same
ICV may be the same
PIH may be differ

my question is: Is it possible for two or more invoices to be saved in the taxpayer’s account at fatora portal with the same UUID number???

If yes, so what is the benefit of UUID???

Please help us
