In FirstWave, illagers wear SecondWave‘s golden armor, and so on, this problem resulted EightWave nohave armors, and FristWave‘s leather armor not function.(i adjusted the probability, even if it's 100% it doesn't help).

I tested it in both 1.20.1(Forge-47.2.21 with mod-1.3.3) and 1.20.4(NeoForge-20.4.204 with mod-2.0.0), same result!
