From a previous question/answer (Why is the billing name missing from the contributions email receipt?) I gather that our duplicated Billing Name might be due to a mistake in the System Work Flow Messages. But we haven't done any customization on any of the System Work Flow Messages.(None of them show an option to "Revert" to original.) Where else should I be looking to find the source of the duplicate name?
