Note: The game curiously does not display successful attack rolls that deal no damage, that's where the question marks come from (the opposition has damage resistance, therefore it is possible to deal no damage not merely when rolling a 1 (-1 Strenght, but also a 2 on the damage roll).
I appreciate your stats, but wanted to focus on this line. This is a bug (or something Larian has decided to change). In 5e, you always do at least 1 damage if you hit. Even if your strength modifier is -5, you roll a 1 on your damage die, the enemy has resistance, AND the enemy has that feat that reduces oncoming damage by 3. You still do 1 damage if you hit.
EDIT: The above is incorrect, don't listen to me. Min damage is 0.
