This is a continuation of what I discovered with reaver mages in
Issue #36396. Like I mentioned there, the issue is more widespread than just the mages. Comparing the inventories of Skyrim bandits with these reavers may be a starting point. The "loot object" count of 2 may be a mistake and was meant to be set to 1. Also, I have no idea whether this is even something that is feasible to fix given that editing templates that are used by multiple NPCs can be a big mess.
Listed below are the additional templates.
