Armor no longer renders on Pillagers and Vindicators

When using in the chat, When doing the /replaceitem command, armor didn't show when Pillagers and Vindicators are equipped armor:

I typed the command:
/replaceitem entity @e[type=vindicator/pillager] slot.armor.chest 1 netherite_chestplate

It didn't show the armor from the pillagers and vindicators.
