Quarterstaff is not a finesse weapon so it use your Strenght which is 11 with 0 modifier, since the +2 Proficiency bonus only apply to attack and not damage then your sheet is correct.
The character you linked has a +0 strength modifier with 11 strength (not the +2 mentioned in your post) and a +2 dex modifier with 14 dex. So the calculation, as plaguescarred said, is correct with a +2 proficiency + 0 strength modifier to hit and a +0 modifier to damage. You can't use dexterity with a strength only weapon - it needs the finesse property. If you equipped a dagger it would be +4 to hit and +2 damage since it would be calculated using your dexterity.
Hello
I build a sorcerer who has a +2 STR modifier. Equipping a Quarterstaff shows its damage as 1d6 (1d8), but doesn't add the STR modifier.
My fighter who is proficient with Simple Weapons, however, is getting the damage bonus.
Is this a bug or am I missing something?

If you link to your character sheet it makes it easier for us to have a look.
Seem like a bug as.you should have a +2 damage modifier with it.
Something odd might be going on. If you post the link to your character sheet someone can take a look.

Interesting. I just quickly built a sorcerer and added a quarterstaff and it shows the strength bonus
Sorry I completely missed that my str is 11, when I change it to 12 I get the bonus.
Thanks!
