Times mined statistic displays wrong value for some blocks

The times mined statistic for blocks with multiple block types does not display the correct value. Torches for example have the types "torch" and "wall_torch", but only the statistic for "torch" is displayed in the GUI. The expected behaviour would be to display the sum of "torch" and "wall_torch".

A few other examples of blocks are: signs (oak_sign, oak_wall_sign, ...), cauldrons (cauldron, lava_cauldron, powder_snow_cauldron)
