I have noticed that the names for some fields in GivingData are not standard everywhere. For example, it appears that the field name for the request title is ProjectTitle. And it appears that way in the Word mail merge fields.
However, the "Insert Field" option in the batch email templates lists it as Request Title.
But you can see that the "Request Title" in the insert field, is the ProjectTitle when inserted:
It just means you have to remember which one to look for in which place to get the same thing.
There are some other examples of that a well.
