Correct ...
@canadalove85 .. please take note, if this is your work documentation, for which you are claiming points, only then would you need the work reference letters. Also, I think, if it is for work history, it does not technically ask for location. so I am presuming that this is a situation where you have only one entry for work history, but two entries for personal history since personal history asks for location.
But if you do not have this employer/role in your work history section (not claiming points for this work, thus only in personal history), then I would not suggest attaching work reference letters.
