Larian calculates the Sneak Damage wrong.
For 4th level a rogue should get +2d6 sneak damage once a turn.
So let's assume your rogue is lvl 4 and has 18 Dex.
So for the damage, if you are hitting a target with a dagger (1d4 piercing) and are eligible for a sneak attack, the damage should be:
1d4 + 4 (ability modifier bonus) + 1d6 + 1d6
The last two +1d6 are of course the 2d6 sneak attack damage bonus.
