Death Knight class filter not showing 2h Swords

[remmarcoux]

Module: Atlas Loot WotLK
Category: Death Knight Class Filter
Loottable: All of ICC and other Raids
Items: All 2h Swords

Additional context
All 2h Swords do not stay highlighted when filtering loot by the Death Knight class. This can be easily see with "Glorenzelg, High-Blade of the Silver Hand" in the Lich King 25 and 25 (Heroic) loot tables or the Citadel Enforcer's Claymore from the Lord Marrowgar 10 and 10 (Heroic) loot tables. Death Knight 2h swords should be there since they are all usable.
