Don't see "items with duplicates" in Watchtower

@lesster

The "Items with duplicates" tile won't appear in Watchtower if you don't currently have duplicates. I'd suggest making a test item, then right-click it and choose Duplicate (choosing the same vault in the pop-up that appears). You should then see the "Items with duplicates" tile in the Watchtower tab. Let me know if that works or if you need any further help. :)
