I am aware that there is a bug with the attributes in the sheet. It was introduced with the last batch of updates, and it will go away with the next one. Everything appears correctly on the sheet, but any rolls with the Dexterity or Charisma modifier are off. Rolls using Dex are instead using Cha, and rolls using Cha are instead using Wis. Str, Con, Int, and Wis rolls are unaffected. Hovering over inline rolls will also display a "floor(14/2-5)" value, which will also be fixed in the patch. For a temporary fix, I suggest putting your Dex score into your Cha (and recording Cha so you can put it back). That will solve the issue of ranged attacks, as long as you don't need to make a Charisma check. I'm sorry for any groups which have been affected by this.
