This is a problem with partial-completion.  You can continue with C-q
SPC, or move back before "letter" and insert either "capital" or
"small".

Here is a reduced testcase:

(completing-read "Type a SPC b TAB: " '("a 1 b" "a 1 b c" "a 1 b d" "a 2 b" "a 2 b c" "a 2 b d"))

The minibuffer contents become "a SPC SPC b", indicating that a word is
missing between "a" and "b".  Either partial-completion should move
point back to where the word is missing or accept SPC as input.

Andreas.
