[racket] Difference when choosing language vs. #lang line

When I run:
-----------------------------------
#lang htdp/bsl
(require 2htdp/image)

(circle 50 "solid" "blue")
-----------------------------------
I get '(instantiate (class ...) ...) rather than the pretty picture I expect.

It works fine, however, if I choose the language from the menu and
leave out the #lang line.

Intended behavior or is a snip not getting loaded that should be?
