The bug
What I expected to happen was for me to able to replace the armor with another piece of armor, like on the Bedrock edition of Minecraft.
What actually happened was that did not happen and it did not do anything when I right click to try and replace the armor.
How to reproduce
Grab 2 different pieces of the same type of armor, eg. 1 netherite chestplate and 1 diamond chestplate
Put one of the pieces off armor on the armor slot in the inventory
Put the other piece of armor in the hotbar
Select that piece of armor and right click
I can confirm this, but this parity issue was introduced before buzzy bees (1.13 on bedrock), but this may actually still be valid, since it was considered a bug on bedrock. MCPE-35579
