According to the spell details, Chaos Bolt should deal 2d8 + 1d6 (+1d6 of additional damage per level when cast at higher levels).
However, in the list of prepared spells, Chaos Bolt is listed as only dealing 2d8 dies of damage, regardless of level it is cast at. When clicking to roll damage dies, it also only deal 2d8 damage.
