using "Shift+Space" in org-mode capture minibuffer

Question

Using Emacs 28.2 (graphical, not text mode) from https://emacsformacosx.com with org-mode 9.5.5 and ivy.

When entering a task description in the mini-buffer via org-capture, I occasionally enter both the Shift and the Space keys instead of just Space. Rather than just putting a space character into the task description, this blanks the entry so I have to re-enter the task description from scratch.

Not sure if this is an org-mode setting or plain Emacs, but could anybody point me into the right direction on how to change this behaviour so that Shift+Space yields in a simple Space character in this context?

EDIT Capture template is as follows

       (global-set-key (kbd "<f6>") 'org-capture)
       (setq org-capture-templates
         '(("t" "Todo (work)" entry
            (file+olp "~/Workcloud/org/WORK.org" "CAPTURE" "Org-Capture")
            "* TODO %^{Task Description}" :prepend t)
           ("n" "Note (work)" entry
            (file+olp "~/Workcloud/org/WORK.org" "CAPTURE" "Org-Capture")
            (file "~/Workcloud/org/capture-note.txt")
        :prepend t)))

EDIT2

Inspecting the key bindings in the minibuffer, I found this

S-SPC runs the command ivy-restrict-to-matches, which is an interactive byte-compiled Lisp function in ‘ivy.el’.

It is bound to S-SPC.

(ivy-restrict-to-matches)

Restrict candidates to current input and erase input.

So I think I know where to look next.

Answer 1

So it turns out that ivy had a keybinding for S-SPC in the minibuffer, which I simply did not expect (S-SPC is not a typical combination I would rebind, but maybe that's just me).

The easiest way to discover this is to press C-h k in the minibuffer, then S-SPC, and Emacs will happily tell you about the binding.

So I ended up adding (define-key ivy-minibuffer-map (kbd "S-SPC") nil) to init.el, which unbinds this. Of course you could bind the function to a different key combination, but I had no use for it.
