Cherry signpost uses recolored version of mangrove signpost texture, despite having a different log texture

Cherry signposts (the stick that holds the actual signboard up when you place it on the ground) use the exact same texture as mangrove signposts, only recolored purplish. This is inconsistent with all the other wood signposts which have textures that fully reflect their unique log textures. Cherry and mangrove logs have different textures, so their respective hanging signs should reflect this, yet they don't.
