We have a different title for the (pay later) offline receipt contribution email (civiContribute). The first email with the data necessary to make the payment has a title saying something and the payment confirmation email (sent afterwards) title says something else. I do remember this having been changed by us. However I cannot remember or find where. We would like to change the first email title again, in order to say something else.
I've checked the system workflow message templates and the localisation files at transifex and the change does not seem to have been done there. Is there a translation file for tokens? And if so, where can it be found?
