Between 17w47a and 18w01a (inclusive), wall signs, torches and skulls/heads used the translation key "block.minecraft.<wall id>", now they use "block.minecraft.<standing id>".
Steps to reproduce:
Replace <standing id> and <wall id> with the values matching the below table.
/give @s minecraft:diamond_axe[minecraft:can_break={blocks:["minecraft:oak_sign","minecraft:oak_wall_sign"]}]Observe how the 2 match.
/tellraw @s [{"translate":"block.minecraft.<standing id>"},"\n",{"translate":"block.minecraft.<wall id>"}]Observe how a different string is printed for the wall block.

This also affects wall banners, but those are tracked in MC-124142 and are missing their wall variant translation keys, unlike these blocks.

Relates to MC-124142 and MC-122579. (Grum's fix is to blame here.)
This has been an issue since 18w02a, and went unnoticed for all those years!
