Widget setting for module Node Reference

I have a question:

In Story content type, create a CCK Node Reference as "author". Config Autocomplete for the matching is "Starts with".
In Page content type, add Existing field "author" and then config Autocomplete matching the is "Constrain".

But when I creating node in the Page, the "author" field is "Starts with" not "Constrain".
If I change the type of story is "Constrain" and Page as "Starts with", when add node in the Page is "Constrain".

I keep settings are different for each Content type when create node
(In widget settings work fine)
Please help me.
