Functions for creating a new account

yes, this is normal, hence the term "default", that is, the most common function or profile for this resource.
Since we can change profiles at each assignment and we can assign the same resource with several functions to the same activity, we must select a basic one. The default one.

To best manage the functions, I advise you to go to the resources screen and not to the user, which only records the default function. and you will find the necessary information for managing functions in our manual.
