I searched and didn't find this mentioned autocalcuated values I had one character with two classes, 5th Monk, 2 Warlock, the level on the attributes page got set to 6.  I had to change it manually to 7.  I don't recall if it displayed correctly on the first page. On a 7th level Wizard character, Spells known end up being 4 Cantrips and 0 Spells.
