When adding an unarmored defense calculation for a homebrew race - in this case, the Zendikar Goblin's Grit feature, the character sheet displays the armor calculation as a bonus rather than a separate calculation. The test character I was using the Barbarian's unarmored AC calculation, but the racial feature interacted with this by treating the racial AC calculation as a bonus, instead of defaulting to the Barbarian's AC calculation.

The feature is working correctly, you just need to change the values.
The sheet treats AC as 10 + DEX + bonus.
And You set the bonus as 11 + DEX. (AC will = 21 + DEX*2)
Simply change the fixed value to 1 and remove DEX ability score. (AC will = 11 + DEX)
