[18w47a] command broken...

/execute if score Stone Bank <= Stone1 Comparisons run setblock _ _ _ redstone_block      of course the _ _ _ are the

chords, but it just gives a blank command block texture where the output should be. I even made the scoreborards, and they were dummies.
idk if this is intentional, or a bug, but I also tried it with the replace at the end of the setblock command. plz fix.
