duplicate user files
 

How can a person delete duplicate user files that were created as corrections were made in the editor? I keep getting Fail to test notifications based on data I created but is not related to the Item being created. I created Armor piercing arrows which are working fine, but when I tried to create a new Item Power it wont test because if a conflict on lines 03, 16 and 26. I do not get how this is happening in 2 completely different categories with two completely different unique id's.
