"When you have multiple main, quick create or mobile forms for an entity you can assign a form order. The form order determines which of the available forms will be shown by default. The available main or mobile forms can be further controlled by assigning security roles to forms. See Control access to forms for more information.
You cannot assign security roles to quick create forms, so the only form that will be used by everyone is the one at the top of the form order."
This means that although it's possible to create more than one Quick Create form, everyone must use the 1st one. Why then have you allowed us to create multiple forms?
Bring Quick Create forms in line with other form types: enable users to switch between forms, and enable them to be controlled by security roles.
