help with lootfilter displaying info on runeword stats

[zwala]

Hey i want to display the roll for lets say bonus to attack rating on insight
this is how i tried to do it:
in item-modifier.json i added an entry wich is a copy of the original attack bonus to attack rating text exept it has a different id("30002"),key("InsightA") and enUS text where i added 200-260 wich is the roll for that stat on insight
in properties.txt i added a property it has the same values as the normal att% exept for code("attinsight") and stat1 ("insight_attack_rating")
in itemstatcost.txt i added an entry wich is a copy of the item_tohit_percent exept the stat("insight_attack_rating") the id("371") and the descstrpos/descstrneg("InsightA")
in runes.txt i went to the insight runeword and changed the att% to attinsight but in the game it still displays att% not the new property i made
sorry for my bad english but does anyone have an idea on how to fix this ?
