The default leave profile is always used as the base for any other leave profile.
When a new profile is created (under Other Leave Profiles), this default profile will be copied. If there are no Other Leave Profiles created, then the details contained in this profile will be used. Therefore its best to define the default profile to be properly defined to begin with and that will result in less editing later. Any changes to the default profile does not make changes to any profiles created before the changes to the default.
The name of the profile can be changed, however it will always show [default] in the name display.
If extra leave categories are required, then first add the category name in Leave Categories, and then the name will appear in the default profile listing (below) and can be edited.
If many profiles are planned, it may be easier to not assign users to this profile but to create specific new profiles, based upon this profile.
