Netherite Armour has small durability then it should.

When i make a sword, it just has close to 2000 durability.

But netherite armour gives each piece like 400-500 durability.

And i'm guessing, that shouldn't be the case right?
Could you please fix it? We play with friend on 20w16a.
We had to switch back to this version, because my friend had a problem with repeaters or whatever in the new version.
Could you please make 20w16b?
