Ah!
Thanks.
Yes, I deleted two entries (1x copy to... from the group Copy to and 1x move to.. from the group Move to)
they were pointing to a drive that did not exist anymore
By doing so, all the other items:
submenu move to (5 incl a rename submenu (6 items)
submenu rename (15 items)
and 11 other items
moved to the submenu under 'Copy to'.
Restored an Opus backup.
Am a bit unsure how to delete them without other items / groups disappearing into Copy to
