In one of my instances of v8.0, I have this field on customer invoice form, but none of the inherit views or the view itself has this field in it, the field is only on invoice supplier forms, how is this possible?

The problem with this is that, for example in invoice generated from pickings, the account move lines references are wrong since should be invoice number and not the 'name' of the invoice, field which is filled with the same value of the 'origin' field of the invoice, (for example: OUT0001,OUT0002)

I guessed it has to be some of the modules installed on the instance, but i can't localiza where the field is added to the view, and so on, where the name field is filled with that data
