Maybe it was locally cached ?
An other question, are you sure each packets ends in a class? I never see
your marking rules and you don't specified a default class.

Don't worry about these numbers :)
ctokens < 0 means the class sent more then the ceil because parent child
classes are asking too much bandwidth. Same for tokens and rate.
