Little Genius - Linux (.deb) version v0.5.6 - Farilwyd doesn't show all tempers in the Item Chest

I've equipped one of my Farilwyds, and checked it in the Item Chest section of Little Genius. It doesn't show the Sullying Force temper. The Swooning Blow and the double Fortified temper shows up as they should, but the Sullying Force is missing.
