According to the game rules on Chapter 2, weapons Proficiency shouldn’t affect the bonus modifier.
But on the character sheet it does change according to the character’s Proficiency.
"DAMAGE WITH MODIFIERS
Some damage rolls come with modifiers, such as “2d6+2” or “3d8+5.” In these cases, you roll the dice, add their values together, then add the modifier to that total. This modifier is not affected by your Proficiency."
which class are you using and what weapon, warriors get a bonus to damage equal to their level, which could look like it’s adding proffiecncy
Yeah, I just noticed XD.
Was about to delete the post. Thank you for the heads up Jones!
It could be nice if there was an indication from where the bonus comes from to avoid confusion.
indeed it would be nice, lots of other things like evasion and armour thresholds do
The issue is you cant check the calculations on anything which automatically rolls dice 
Given a choice Id disable the dice - they are no use to me - but there is no option for that.
