The bug

When configuring debug settings for carvers, and setting the block's name to a block that updates with /setblock (see list in MC-31100), an acacia button is placed instead of the desired block.

In the screenshot attached, although I configured the settings with redstone wire, acacia buttons were placed instead.

How to reproduce

If these reproduction steps are more complicated than needed, sorry – I am not good with datapacks!

I was able to reproduce this issue by setting up a datapack using slicedlime's example worldgen settings (here). I added "debug_mode": true, to the cave carver file under "debug_settings": {, and changed the default block placed to redstone wire (minecraft:redstone_wire) instead of crimson button. I then created a world using the datapack.
