Currently, if a dimension is based on an expression, the filter bar displays the expression instead of the title (or label) of the dimension. Also, the filter bar displays a dimension's field name instead of the title (or label). For example, I have a field named "MedicalClaims.Billing Provider" and I have saved a filter pane in my master items with the label "Billing Provider (Medical)." The filter bar shows the field name while my filter pane shows the label. It's especially confusing when a dimension is built with an IF statement (like "=If(..."). No one can hope to read it.
It should show the title (or label). That way it's obvious to the user which filters are applied.
