Hi,
If nothing was changed nowhere, it should work all right. If this is only happening on the new product, then the custom field might be missing from them. It is also possible that the new attributes are now stored as taxonomy terms. Try using this advanced title field, to see if it makes any difference:
{titlefield}[ - <span style='text-transform:uppercase'>{pa_esittaja}</span>][ - <span style='text-transform:uppercase'>{__tax_pa_esittaja}</span>]
