AR not following sequential numbering

SOLVED

We did the update to 25.3.84, we archived payroll for 2023. Now I am trying to create AR invoices for our customers but it is not following the sequential numbering anymore.

I am creating invoices today and usually after creating one invoice, the next one is a sequential number higher. However today, it assigns a random number to the invoice. 

Right now I have 2023182 but when I create a new invoice instead of 2023183 it gives me 600721037 which is not the next number.

Thank you for any help.
