org-agenda-deadline-leaders (e.g. "In %3d d.:") missing from org-super-agenda view

[Gerald]

As the titles says, I can't get org-super-agenda to display the number of days until a future deadline. I have set DEADLINE and SCHEDULING information to appear in org-agenda-prefix-format, but nothing relating to the deadline appears. On Doom Emacs.

org-agenda-prefix-format
'((agenda . "%?-12t% s")
(todo . "% s")
(timeline . " % s")
(tags . "%s %i ")
(search . " %i %-12:c "))`

Any pointers would be highly appreciated!

This package has nothing to do with formatting of items.
