@lubos  
Greetings

The problem is as follows: When I edited the invoice, entered the Invoice Subtype data, and clicked “Update,” the invoice number changed from one number to another.

It is possible that the **Reference** is checked during editing, so the system will create a new reference number when updating.

There’s your issue.

Whenever you check the Automatic Reference field, a new number is assigned, so if you don’t want the number to change don’t do that.

Now you need to undo that batch update and redo it again but this time keep `AutomaticReference` field set to `false`.
