Notice a new folder called babel-stable-nnn (some randome 3 digit

I think these should be created in my /tmp/ folder, not the folder
containing the .org file.

Sometimes they ARE created in my /tmp/ folder.

Thanks for reporting!

Could you open one of the folders where babel-stable-nnn directories are
present and then run M-: (temporary-file-directory) ?
Is the printed output "/tmp"? Something else?

Thanks for responding Ihor.

Opening e.g. "/mnt/data/src/learning/zig/zig_notes.org"
In the buffer visiting zig_notes.org:
M-: (temporary-file-directory) -
"/mnt/data/src/learning/zig/"
The variable though:
temporary-file-directory -
"/tmp/"

Looking at that function and from the same buffer I also checked:
default-directory -
"/mnt/data/src/learning/zig/"
mounted-file-systems -
"^\\(?:/\\(?:afs/\\|m\\(?:edia/\\|nt\\)\\|\\(?:ne\\|tmp_mn\\)t/\\)\\)"
(find-file-name-handler default-directory 'temporary-file-directory) -
0

I wondered about a buffer not visiting a file. In my default *scratch* buffer I get:
(temporary-file-directory) -
"/tmp/"
temporary-file-directory -
"/tmp/"
mounted-file-systems -
"^\\(?:/\\(?:afs/\\|m\\(?:edia/\\|nt\\)\\|\\(?:ne\\|tmp_mn\\)t/\\)\\)"
(find-file-name-handler default-directory 'temporary-file-directory) -
nil

The same in some *help* buffer though _except_:
(temporary-file-directory) -
"/mnt/data/src/learning/zig/"
