Bugs from the furnace arrows

I've been talking since the launch of the nether update, that the furnaces have a problem that consists of: when I'm going to bake something in any furnace in the games, simply, the arrow remains on, it seems that something still burning in the furnace, however, no there is nothing, only when I close the game and open it again that it stops, you need to fix this bug, which is not now that I'm talking about it.
