Would the correct form of the key be _wpuf_form_id or wpuf_form_id?

Tareq, when I set the meta key _wpuf_form_id using Gravity forms, the default form ID is not set, although I can see the correct value of that key when I manually set the form ID in the post and then use the WPUF editor to view the results.

Do I perhaps need to manually set a different key at post creation? I do see two new custom fields are now available in the post custom field dropdown menu: wpuf_form and wpuf_form-settings.

Thanks.
