Using iron or netherite sword with the galena gauntlet does not appear to be applying the enchants on the swords properly. Two notable examples I tested:

• Swords enchanted with fire aspect do not light the target on fire as they should.
• Swords enchanted with sharpness do the same damage as without sharpness (i.e. a sharpness 5 netherite sword kills a zombie in 3 hits, same as unenchanted, when it should kill it in 2).
  This issue does not appear to affect pickaxes or other tools, as using a pickaxe with silk touch with the gauntlet on stone still drops stone as it should.
