Custom menu link does not show up under "List links" but is in the database I have three menus with six links each using the i18n module.

All of these links are to panel pages.  On one menu, however, there is an additional link to another custom panel that does not appear in the Menu UI (under List Links)  but is present in the database (I found it in the menu_links table).

When I go to the panel of the ghost link, the option for showing a menu link is disabled.

How can I put this link back in the UI?  Or should I simply delete it from the database and re-create it in the UI?

EDIT: I tried adding the link in the menu manually, but then it shows up twice.
Simply go to the menu and add that link in the menu and it would start showing up.
