Views Label Name and Display Name Confusion

I've always thought that in Views, the "Label Name" refers to the Label Name of the field in the form. However, I just realised that this is not so. For example, I have a form field with Label Name MOE (variable name also MOE). In the corresponding view, I initially have Label Name "MOE" and Display Name "MOE". I changed the Display Name to "Score1". The next time I came in the view, I found that the Label Name has changed to "Score1", and display name is "Score1".

This is silly. The Label Name should NEVER change - it should always correspond to the form field name.
