I don't think these are really "labelled IF statements" - what the creator of the template has probably done is to replace the result text of the IF field by the text they want the user to see. If you preview the merge document and move to the next or previous record, my guess is that you will see the text change to be the result of the field, and when you move back to the record you started with, you will no longer see this placeholder text.
From a programming point of view, you could for example replace all the result texts with your own "placeholder" using, e.g.
Dim f As Word.Field
For Each f In ActiveDocument.Fields
If f.Type = Word.WdFieldType.wdFieldIf Then
f.Result.Text = "my placeholder text"
End If
Next
But in fact, you can replace the result text manually by, e.g. clicking inside the text, typing your own text, then deleting all the old text (carefully, or you may delete the field). If you do that, this isn't a programming question and would be out of scope for StackOverflow.
