possible missing "sign up" link in nav menu

hi,

using the default CoursePress theme there is no "sign up" link in the default menu.
is this how it is by default ?

i ask for a couple reasons;
- this is an obvious/important link and i just assume it would be there in the default theme/menu.
- in a local test site using the Kleo theme i see options in the menu for CoursePress (screenshot), but its not available in the same menu section of another site using the default theme or even other "twenty" WP themes.

i see there is a "create an account" link on the login page which goes to the signup page which is great.
but if i create my own link for sign up it won't have an icon to match the default CoursePress theme in the main nav.

i have "display menu items" selected in the CoursePress settings.

i am also thinking this may be dynamic but even when logged out i do not see any signup in the menu.

1 - shall i delete and reinstall the plugin or is it that this sign up simply is not part of the default menu ?
2 - how is it that i see extra options in the menu for Kleo theme and not other themes ?

kind regards,

RC.
