Some Copper Blocks' subtitles don't work

Note: the regular door is fine

It should just show "Copper Trapdoor Creaks"

The subtitle was "subtitles.block.copper_trapdoor.toggle"

Steps to Reproduce:
Place a Copper Trapdoor (waxed or unwaxed, any oxidization) and open/close it lol

 

Edit: The copper bulb also does a similar thing (accidentally pressed F3 while trying to screenshot)
