Warlock Spells Known Error

I have a Warlock who, at both 3rd and 4th level, states on the character sheet that I have access to 2nd level spells, but my spells known only allows me to pick my cantrips and 1st level spells. I am unsure yet if this continues to apply at higher levels. Also, it would be nice if we could add the bonus spells provided by our patron.
