Custom Fields

Hi,
you were so kind as to provide the legacy extensions for testing the new 7 version. One important thing for us, however, seems not to work any longer:
We use the advanced custom fields (ACF) plugin for additional user profile fields. This works fine for the backend user profile page, as well as for the themed register page (using theme my login 7). However, the fields are not shown when we use the profile page extension? Any ideas?
Your’s
