Are you saying you have multiple forms on the same page? The allowance of multiple formkeys for the same form was not really intended for the case of multiple forms on the same page -- rather, it was intended more for the case where the user might open up the same page in multiple browser tabs and end up submitting the form on some tab other than the last one loaded. When you have multiple distinct forms (even if they happen to contain the same set of fields), the proper approach is to use different formnames for each form (formkeys are unique to each formname, so you can have as many as you want).
