UPDATE: This is considered a feature request, so this is invalid. Please ignore.
This bug affects 22w16a and 22w16b, and any future version at the moment.
In 22w16a, Mojang released new paintings, those being Earth, Fire, Water, and Wind. However, they are inconsistent with current paintings.

@Greymagic27 That’s true, however if it is getting added officially, it should be changed to match the other paintings.
Seemingly referring to the art style (looking at labels and the comment), in which case this seems like a change request, rather than a bug.
I believe these paintings are inconsistent as they're the unused ones from Bedrock Edition so they've not been adapated for the current style of paintings
