Sandstorm - Clean email sent, but contents (headers/body) mixed up

Soft Release 9.400-9

Have turned on Sandstorm for Email, and just received one that had been classified as Clean. Unfortunately the received email had lots of the headers appearing in the body section, and the files were shown as text in the email, rather than as attachments:

Is the problem that a new line was put before "--- Sandbox result ---"?

(Also, none of the Email files get listed in the Sandbox Activity section).
