The nature spell Earthen Crust isn't in the spell filter "Boons." (Tested: T4)

The blight spell Malady isn't in the spell filter "Banes." (It is both a DoT and a debuff.) (Tested: T2)

The blight spell Dispell and the nature spells Root and Patch of Bramble aren't in the spell filter "Banes," where one could argue they should be.

The spirit spell Self-Sacrificium isn't in the "Healing" filter. (Tested: T2)

The spirit spell Ethereal Paroxysm isn't in the "Effects Over Time" filter. (Tested: T1-3)

Repeaters with the Range tech (which adds a recycle) still appear in the "Repeatable" filter. May or may not be fixable with current tech, but there it is.
