I can not describe you what we did since I figure it out because my financial statement didn't balance so I start looking where was the difference at i found there was a journal entry with no account but with balance. I can not tell you how it happen just show you the journal I already attached.
Maybe after save the journal the account number in the JE was deleted by mistake.
We never delete the account in the register, is no about that, just the account number in the journal entry is missing
