When filtering autocomplete by a view #default_value always be the entity title instead of the custom view result (e.g. a field on the entity)

please look at these screenshots.
When I use entity reference in a views and autocomplete widget, It worked well.
but when I edit node, it chenged referenced field value as a screenshot 2
Other widgets worked perfect like list or select box (didn't change its value) only has a problem with autocomplete widget.
It automatically changes its value to original(referenced) title I think , but I'm using profile2 I can't change its title.
How can I use autocomplete widget without this problem?
or can I change profile2's title what I want?
