The center box in 'last' is fill, created by {: on the empty (boxed)
list in words, and it is a:, which has (empty) boolean contents.
What you have done is equivalent to
3 {. > {: ;: ''
0 0 0
To fix it you can use
3 {. > {:!.(<'') ;: ''

I was working on code analysis a couple of months ago, and thought
about code display and which elements needed blanks around them.
Without that side trip I might not have noticed that I was getting
numbers instead of characters. The problem was easy to get around,
just test for and ignore the empty lines, so I got on with my work and
left a note to report it later.
I originally saw the issue on Android 901, and have just confirmed it
on Windows 902 beta, both 64-bit if that matters.
