Say the username field is 12 characters long, but the current username is "BOB" - when you SCATTER it,

m.username = "BOB         "

- i.e., PADR("BOB",12)

So when you replace it, only first 12 characters get put in, since that's all that will fit.
Note that you'll also only get the first 12 characters if m.username is last in the expression - it may not appear so, however, unless m.username is long enough to be truncated.

You can do either of the following to join them regardless of righthand spaces:

REPLACE username WITH TRIM(m.username) + "Closed Account"

or

REPLACE username WITH m.username - "Closed Account"
