In my mind if I replace their armor then only the armor I equip them with should drop. For example if I give a dwarf a mith helmet and it gets killed then it should drop that mith helmet and/or the other remaining dwarven armor pieces. It doesn't seem like it should drop both the mith helmet and a dwarven one unless that's intentional. Aha. That sounds like it's just intentional. When you replace a hired unit's equipment, it still carries its original equipment - this is so that it's not left helpless if you want to take back your equipment or change it.

When a hired unit with replaced equipment dies, it should drop all of the equipment you gave it, 100% of the time. In addition to this, it also has the standard chance of dropping whatever "base" equipment it has, as do all NPCs. Since all its drops are independent, it even has a rare chance to drop its full armour set.

So if that's happening, there is no bug. But if it's somehow duplicating the items you gave it, then that definitely is a bug.
