Evasion Calculation on HoD Character Sheet Seems Wrong?

Hey all,

I'm transferring a character to the built-in character sheet on this site, and the Evasion seems wrong.

Its a Drakona/Infernis Wanderborne Seraph (Divine Wielder). His equipment is a Gilded Falchion and Improved Tower Shield. No Armor (Bare Bones). The Evasion breakdown on the character sheet shows the following:

Evasion 10
Seraph (+9)
Advancement: Evasion (+1)
Offhand Weapon: Improved Tower Shield (-1)
Other engine modifier (+1)

The "Other engine modifier" is a mystery. Tracking the character growth in Foundry, his Evasion should be a total of 9.

Any suggestions?
