Is this an error?

Shouldn't the two red circles MATCH? How can the session say it netted $423 when its own graph shows ~$170?

You played that session over midnight (it appears) and the date filter you applied will filter out individual hands that were played on the next day (after midnight) but this only affects the hands and graph, not the session totals (see the link on the General tab when you have filters applied).
If you use the Settings button to set 'my day starts at' to a time you never play, say 5am, then you shouldn't see this.
