Campaigns field is not found in Sugar Fields of Edit layout

[Cossbie]

Campaigns field is new field in Contacts/Leads/Opportunities module in SugarCRM4.5.1.
It's a very good!

I'm editing layout of contacts.
But campaigns field is not found in Sugar Fields of Edit layout.
I attache its image file.

If I move campaigns field to Sugar Field and save,
then campaigns field is gone.

Thansk for your help.
