NPC Roll button uses incorrect modifiers

So my main PC has a Dex of 12 (mod of +1). I clicked the Roll Dexterity Check button for Eadwin (NPC). He has a Dex of 16 (mod of +3). The custom roll screen came up and showed the mod of +1 for my main PC. This needs to reflect the actual mods of the person you’re rolling for.
